Switch stack connectivity question

x.x.x.10 = stack 1
x.x.x.11 = stack 2
my question since i have been thrown to the wolves is (with very little experience): I am at one site with 2 stacks. Is connecting stack 1 to stack 2 done with a crossover or straight through cable? On stack 1 I have 6/0/19 and 6/0/20 being used for avaya vm erver and avaya ip office. So I need to make sure that second stack can communciate to number 1 in order for the prots on the second stack to recognize the vm server and ip office locations. I'm a little confused. I know I shouldn't use a stackwise cable. Any help would be appreciated.

Not to be overly technical or picky, the term "stack" refers to the feature that the 3750 is capable of and stacking this platform would require a "stackwise" cable. It should come with the switch and it's silver. you connect the 3750 through stack port in the back of this switch. Now, if you are simply connecting two switches together, you will require a cross-over cable. A good rule of thumb is when connecting two alike devices you will need cross-over, like router to router or switch to switch. If they are not alike then you will need straight.

Switch inter-connectivity question

Good day to all. We have a small LAN with less than 10 switches total. Including all the network printers and PCs and servers there are about 70 nodes in this building. In the data room, there are (6) 24-port Catalyst switches. I am trying to determine the best way to inter-connect them. 2 of the switches are c3750x and are stacked. 2 are C3560X and cannot be stacked, and the other 2 are C2960G and cannot be stacked. Also, there is a C2960G in another building connected to one of these 6 via a 1G uplink. I wish I had gotten more of the switches with stack capability, but at the time I was not aware of the advantages of stacking.
So... The 2 C3560X switches each have a 10-G network module installed. One of the 2 3750X's (the stack master, call it Switch-A), in the stack has a 10G module as well. In a perfect world, I would take the C3560X (the one that is layer-3 with routing enabled and also the default gateway), and connect all the other switches to that one, and use both the 10-gigabit uplinks and then use 1-G uplinks for the rest. But if I use the 10-G ports, then I cannot use the other 2 1G SFP ports in the network module. So I am limited to 2 10-G uplinks per C3560 switch. I can't connect all the other switches to this one unless I used some of the standard (non-SFP) ports.
So here is the way I have it set up right now: there is a 1-G fiber uplink from another building and the fiber is FDDI so it is not possible to use a 10-G uplink between the buildings; they are too far apart for FDDI. We might run some OM3 fiber later, but for now, the 1-G uplink is the best we can do. So the 2 buildings are connected using a gigabit fiber uplink with SFP ports, and the fiber coming from the other building is connected to the C3560 that is not the default gateway. The default gateway switch, call it switch-1, is using both the 10-G uplinks and has one 10-G port connected to the master in the 2-switch stack, (one of the C3750X's, call it Switch-A). The other 10-G uplink goes to the other C3560X, call it Switch-2 (Switch-2 is the one with the fiber uplink from the other building). Switch B is the stack slave and is only connected via the stack cables. The other 2 switches are C2960G-24TC-L and one is connected to Switch-A with a 1-G copper SFP uplink, call it Switch-3, and Switch3 is connected to the other C2960G with a 1-G copper uplink. I have attached a basic diagram.
So... my question is, without spending more money, is this the best way to connect them? I could use more of a hub and spoke topology if I did not stick to SFP ports for all the up-linking. It was my understanding that the SFP ports are the best ones to use for uplinks. But due to the limitations of the network modules, I could not connect more than 2 SFP uplinks from a given switch, or 3 in some cases where only 1G uplinks were used.
If we did not mind spending a few more thousand (I would love to run OM3 between the buildings and get the speed up to 10G), so if we had another 5 to $10,000 to spend, would it be worth getting a switch full of fast SFP modules and using it to uplink all the other switches (a total of 5 counting the link from the other building and not counting Switch-B since it connects via the stack)? Everything is working well, so it might be better to leave it alone. Any helpful comments and/or suggestions are welcomed with a heaping helping of sincere appreciation!
Thanks!

What you might consider is using your dual 3750X stack as the physical core and as the L3 router. All your other switches (except the off-site switch) would have dual port channel links, one link to each 3750X. This provides core and L3 redundancy and can provide more inter switch bandwidth.
For you critical single home devices, such as your Internet and off-site switch connections, you can have a logical configuration "mirror" port ready on the second 3750X stack member, so if the member with the active link fails, you only need to repatch. (This can also be use for other critical single homed servers).
On a 3560X/3750X switches you do want to use the SFP ports for your busy ports (because they have their own reserved hardware buffers). However, if you use 10g port, as 10g, you lose half your SFP ports. Without knowing your expected traffic flow patterns, I cannot not say whether using all the SFP ports for dual gig port-channels would be better than having some on copper edge ports and some as dual 10g fiber ports.

Snmp for 3750 switch stack

Hi,
I have two 3750 switch stack together with one ip address mange the stack.
Can I monitor the memory and cpu for each individual switch? what is the oid then?
Thanks.
C.K.

Hello CK,
On the Catalyst 3750, the stack master handles the SNMP requests and traps for the whole switch stack.
The stack master transparently manages any requests or traps that are related to all stack members. When a new stack master is elected, the new master continues to handle SNMP requests and traps as configured on the previous stack master, assuming that IP connectivity to the SNMP management stations is still in place after the new master has taken control.
So to answer your question, with the OID for CPU and Mempory usage the switch will return only values for the active master. The other stack members are hot standby and do not produce SNMP information for CPU and/or Memory.

Removing 4 out of 6 switches in a switch stack

Hi all,
A very simple question for the group (I hope!) regarding 3750 switch stacks.
I've inherited a stack of 6 3750 switches. I need to reduce this to two. All of my active connections have been moved over to the remaining two switches I plan to keep.
Here is the output of the show switch
DASW01_4STACK#sh switch
Switch/Stack Mac Address : 001c.b1d9.cb80
                                           H/W   Current
Switch# Role   Mac Address     Priority Version State
1       Member 0019.2f07.ab80     1      0       Ready
*2       Master 001c.b1d9.cb80     1      0       Ready
3       Member 001c.b1e1.5d80     1      0       Ready
4       Member 001c.b1f6.4a80     1      0       Ready
5       Member 0023.eabd.3500     1      0       Ready
6       Member 001c.0ea1.be80     13     0       Ready
The two switches I want to keep are # 5 and #6.
As you can see, for some reason the master is not on switch 6 even though it has the highest priority. All the switches are connected together with the proper redundant stack cables.
I've never worked with stacks before but would the actions be as simple as.
1. Backup configs!
2. Turn off switches 1 to 4 one at a time an allow for the stack to stabilize after each switch is powered down.
3. Verify that switch 6 is now the master and everything still works.
4. Turn off switch 5 & 6 and connect the stack cables of each switch to each other for redundancy (currently only one cable connects switch 5&6)
5. Turn on switch 5 & 6
Am I missing anything?
Thank you!
-Pete

Leo Laohoo wrote:"Power off the switch that is to be added."But Joseph you are not ADDING switches. You are REMOVING switches from a stack and re-cabling.If one was adding a new switch, then yes, I recommend the new switch is to be powered OFF before connect the stacking cable.
Leo, an excellent point!
Powering of the switch, when "adding" to the stack, no doubt gets it to initiate itself as a stack member.
Re-cabling existing stacks members, shouldn't need that, but the question then is whether the hardware (stack connections) were designed for making "hot" (i.e. both sides powered on) connections. If they are, then you're correct, no need to power off switch 5.

Can't write to flash1: in a 3 switch stack

I have a 3 switch stack at a remote office consisting of a 48 port 3750X, 24 port 3750X PoE, and a 48 port 3750v2. Currently this stack is functioning normally and is running 12.2(55)SE3 (universal on the X's, ipservices on the 3750v2). I want to upgrade to SE8 so that's 12.2(55)SE8 as I see in the release notes there are some vulnerabilities fixed in SSH.
For the life of me, I cannot copy the new file to flash1: which is the 24 port 3750X PoE. This switch has 20 IP phones and 2 Cisco Access points on it and is vital to the branch office. I have spare non poe switches but not spare poe switches (looking for approval), so go figure I am having the issue with the flash memory on this switch.
If I try to tftp the file c3750e-universalk9-mz.122-55.SE8.bin to flash1, I get Error opening flash1:/c3750e-universalk9-mz.122-55.SE8.bin (Bad file number).
I can get the file tftp'd to flash2 (the 48 port 3750X) fine, but if I try to copy it from flash2 to flash1, I get the same error (bad file number).
Cisco TAC reccomened format flash1: , so I tried that and get Error formatting flash1 (Device or resource busy). OK so on my own I figure maybe its corrupt, lets run fsck /test flash1: and see. NOPE can't run that either... Error fscking flash1: (Device or resource busy). Ok now lets see if any other sessions are hung where something or someone has locked flash1... so I run systat and I am the only user on the switch stack. Ok so no one else has a hung connection that may have had a write in process frozen.
So what should I do? The uptime is 30 weeks, 23 hours, 3 minutes. The last switch in the stack, the regular 3750v2 has an uptime of 15 weeks, 1 day, 20 hours, 28 minutes because it was added to the stack back then.
Anyway the network is fine and functioning... just looking to standardize all our 3750's to the 122-55.SE8 release because it is the one IOS that we've had the best luck with.

Well after a few days of SILENCE from Cisco TAC, they got back to me again and said to reseat the flash again! I said tell me how to reseat the flash when it is soldered onto the motherboard of a 3750X switch?
So they responded with this and they are going to replace the switch:
The error message( Error opening flash1:/c3750e-universalk9-mz.122-55.SE8.bin (Bad file number)) indicates that the flash is not visible,
This issue can be solved by the following steps :
Reseat the flash if you cannot,
Format the flash if you cannot,
Replace the device(hardware failure)
As I can see from this case that the device is unable to format the flash, the only way to solve the issue is to replace the switch 1,
I can tell you support has really gone downhilll. So much that I am considering Extreme Networks, Arista and Broacade for an upcoming 10gbps switching project. Another case we had with them was due to a random switch stack crash on 12.2.58SE2. Well they had the entire show tech ouput and they still reccomended to move to 15.0.2SE4. Well that was BAD advice. When you have 6 3750V2's and 3 3750X's in one stack of 9, release 15 doesn't have enough memory to even run a console. We had to break the stack and one by one go to 12.2.55SE8. I don't know what Cisco is thinking. How can they say oh run this release but then they see its a huge mixed breed stack with a large configuration and they don't take memory into consideration? I even asked are you sure, and they said yes we assure you this release will solve your problems.
So between that bad advice and this bad advice, I am really discouraged at throwing more money into "SmartNet" contracts.

Blocked Stack Ports on 2960X-48FPD-L Stack (Unstable Switch Stack!) Spanning Tree?

I am having an issue where 2 2960X-48FPD-L Switches in a redundant flexstack (stack port 1 SW1 to port 2 SW2 and port 2 SW1 to port 1 SW2) ring.
At first running the 15.0(2).EX5 (and earlier EX3, and EX4) version IOS yielded all the ports on the stack master switch refusing to run spanning tree and would only link in amber and not pass any traffic other than CDP information (the slave switch linked in fine).
I upgraded to 15.2(3)E and this solved the problem of the ports not linking in green and participating in spanning tree.
Now, however, about every week or two I lose connectivity to the switch stack and I was able to go to the switch stack locally and found that for some reason the switch stack is blocking and unblocking VLANs on StackPort1 frequently (see below). When I was at the site, I sometimes had connectivity, sometimes not. A stack hard reboot brought everything back up, but this is the second time this has occurred and I would expect the same problem in the next week or so.
Has anyone else run into these issues, and have you found a solution?
I'm guessing that if I either get rid of the redundancy on the switch stack or stack using Ethernet cables between switches the problem will go away, but then what is the point of using stackable switches in a non redundant low speed stack. It seems to me that Spanning tree thinks that I have a spanning tree loop going on with the stack ports which I didn't even think was possible.
What do you think?

Jim,
We have also the same problem with our 2960-X switches (access) connecting to a pair of 4500x (VSS) except our issue is with Portchannel with 2 physical links connecting the 2960xs to the 4500.
If we disconnect one of the physical links from the portchannel everything works fine, but when we connect the same physical link back all users lose connectivity and the physical link starts flapping. Here are some of the messages we see in the logs when both physical links are in the portchannel:
Mar 10 18:00:43 EST: %SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 1 on Port-channel5 VLAN90.

We have upgraded to 15.0(2a).EX5 and still have the same issue.
We have a ticket open with Cisco and have sent them all the logs and debugs and waiting to hear back from IOS developers.

Switch stack IOS upgrade

Hi,
I am planning on upgrading a 3750x switch stack to a slightly newer version.
My question is, would I have to load the new image onto each switch in the stack or just the master?
Thanks,
Waqas

I am planning on upgrading a 3750x switch stack to a slightly newer version
Specify the IOS so we can determine if you are going to a bad IOS version.
My question is, would I have to load the new image onto each switch in the stack or just the master?
1. Download the IOS file with the TAR filename from the Cisco website.
2. Compare the MD5 hash value of this file against the one in the Cisco website. The MD5 hash value must match.
3. Use the command to upgrade your IOS: archive download-sw /destination N tftp:///IOS.tar
NOTE: /destination N - The "N" means the switch members in a stack. If you have three switches in a stack then you use /destination 1 /destination 2 /destination 3.

2 locations, 2 core switch stacks, fibre in between, equal cost load balancing between?

Hi,
We've recently inherited a job that another company was doing, so we've had our hand slightly forced on the kit and overall topology involved, however that's all fine and we can make it work.
This is a collapsed core topology with core and access switches, split over 3 blocks (fibre connections between), one core switch/stack is in block B and the other in block C, with access switches throughout.
They require all access switches to be connected to the Core in B and the Core in C, and then obviously cross connects between the two cores.
They state:
"Core switches shall be linked with 2x 1Gbps links bonded into a standard compliant Etherchannel"
"Uplinks between access and core switches shall be non-blocking - for example equal cost load balancing at layer 3, or layer 2 bonded multi-chassis Etherchannel"
The specced kit for the core are 3850's, in an ideal world I'd use VSS (Virtual Switch System) to achieve the above statements beyond repute; but this is only supported on 4500/6500 and Nexus platforms.
Do we think a cross stack etherchannel (LACP between both core switch stacks) would satisfy the above statements? Or the statements may just be badly worded...
I look forward to your thoughts and views on this! Thanks!

As the others have noted, the 3850s, to stack, are restricted to the length of the longest stack cables.
As you have noted, VSS physical units would allow the "logical" unit to be far apart.
For a "small" VSS core, the 4500-X might be an idea unit. (Other than cost, the 4500 would be a better choice for a core device.)
Something to watch for, or understand, when running VSS, Etherchannel doesn't load balance as it does on a single chassis or stack. VSS will avoid using the VSL cross link unless it must.
As many access switches, today, support basic L3 routing, you might also determine whether a L3 edge would be a suitable alternative choice. It would allow retention of the 3850s and can offer some advantages even over VSS. (Where VSS is very nice [as too the Nexus] supporting servers with Etherchannels.)

ASA , 3750 Switch stack ,Etherchanel cross-stack and HA

Hi Guys,
I have run into a scenario where there they use a switch stack of four 3750’s and two ASA 5540 in Active-stanby HA Pair.
ASA's are connected with 4 interfaces across stack (1 interface to each switch).
1 Etherchannels (4 ports) is configured between ASA and switch. All vlans are terminated on ASA as a subiterfaces.
somehting like:
Port-channell1
no ip address
Port-channell1.10
vlan 10
ip address 192.168.10.1 255.255.255.0 stanby 192.168.10.2
Port-channell1.20
vlan 10
ip address 192.168.20.1 255.255.255.0 stanby 192.168.20.2
..and so on..
There is about different 60-70 vlans currently terminated on ASA.
We found a problem with failover testing:
When we test the failover and fail manually with “failover active” command,
It looks like only 29 vlans can fail to backup ASA instantly , the rest can take up to 5 min.
Is there a limitation for ASA or 3750 etherchannel in this scenario why it would not failover instantly for all vlans ?
Thanks
Martin

sory mistake there :
Port-channell1.20
vlan 20
ip address 192.168.20.1 255.255.255.0 stanby 192.168.20.2

Can I use DHCP snooping and IOS DHCP server on the same switch stack

Hello,
I am shortly going to be deploying a Cisco CallManager solution for a customer whose network comprises stacks of Catalyst 3850 switches.
There is no separate core/server farm switch so the CallManager servers, voice gateways and IP phones will all plug into the same stack and be in the same VLAN (not my choice!).
For security we want to enable DHCP snooping and were planning on using the IOS DHCP server on the Catalyst switch stack.
Will this work? - when I enable DHCP snooping in networks with separate access layer switches I set the uplinks to the core as trusted links.
I am not sure whether DHCP snooping will work in this case. Do I need to set the VLAN interface on the switch as trusted, is this even possible?
Unfortunately I do not have access to a layer 3 switch to test this at the moment.
Thanks

Nope. That's the issue.
They'll sync on a third device acting as a hotspot, but the device sending a signal is not "on" the network it creates so the airport is all by itself on that network. At least that is what it looks like to me. Anyone have another take on it? Seems pretty silly that an iPad can put out a wifi signal, an Airport Express can receive a wifi signal, and yet there is no simple way to get them to communicate under this particular condition.

Cisco sg 100d unmanaged switch not connecting to network

I have a Cisco sg 100d-08 unmanaged switched that had been working just fine for several months but now devices attached to the network thru are no longer on the network. All lights are on indicating the ports are active. Tried power recycle but no joy. When I replaced the switch with an old Belkin model everything works fine. Is there anyway to reset this unmanaged switch or do I now just have an expensive paper weight?

When the management interface is part of VLAN x
Make sure that the management interface vlan id is set to 0 (untagged ) If the native vlan on the switch trunk connected to controller is vlan x. If the native vlan is something else make sure to tag the mangement interface vlan with x.
Another interesting thing that might happen with switch having the following command enabled:
SW(config)#dot1q tag native
In that case all trunk native vlan frames will be tagged , so you have to tag the management vlan on the controller as well in that case.
To be able to troubleshoot such connectivity problem, you should get the output of:
show run int
show interface <\\ > switchport
the latter command should be your best friend.
One recommondation, make sure to tag your management / ap-manager interface with vlan id to maintain QoS limiting based on dot1p values for downstream traffic from the wired side.
In the above scenario , If you can provide the output of show interface <\\> switchport
I should tell you why the recommended action solved your issue based on the above explanation, and if you would like I can maitain the tag for you.

How can I switch the connection pool dynamically during on load happens

HI,
I have two data bases which holds same data. i.e Prod_db, Prod_db1,
I want to switch the connection pool dynamically during load happens
Ex: During load happens i want to hit prod_db1, after load completes i want to hit prod_db. How to achieve this.

create dynamic repository variable for DSN using init block so that value is changes based on your timings and use this in connection pool.
If you use same user and passwords for both the databases that would be easy or else need to follow the same for uid and pwd.
That should work, if not update.

[SOLVED] pulsuadio and blutooth auto switch to connected device?

Is there a way to stream audiochannels automatically to a bluetooth speaker when it is connected?
At the moment I have to change manually in pavucontrol Playback section. Otherwise sound is still played via internal speakers..
Any ideas? Thanks!

running:
plasma-framework 5.6.0-2
libbluedevil-frameworks 5.2.0-1
bluedevil-frameworks 5.2.0-1
bluez 5.27-1
bluez-libs 5.27-1
bluez-utils 5.27-1
sbc 1.3-1
pulseaudio 5.0-1
pulseaudio-alsa 2-3
The bluetooth speaker is a Denon Envaya mini, connected in A2DP mode.
The whole setup is not working realy stable at the moment, sometimes the device is connecting just fine and I see it in pulseaudio, sometimes it doesn't and bluetooth is crashing when trying to connect. Same is true for trying with bluetoothctl, so I guess it's not a plasma problem.. I also tried gut versions for most of the packages (at least for pulseaudio, libbluedevil-frameworks and bluedevil-frameworks).
Anyway. even when connecting is successfull, I still have to set the audiostream manually to the speaker with pavucontrol.
I tried to load pulsaudio module-switch-on-connect in default.pa but didn't see a difference.. I'm guessing this should only autoconnect the speaker when present, but what I'd like to do is to automaticly stream audio to the speaker when connected, not to the internal laptop speaker..

NW 7.2 Visual Composer - Switch off connection pooling

Hello,
I'd like to switch off connection pooling for a VC app running on NW CE 7.2. I found some entries in destination management for my destination system accordingly (pool size, max time .... and an option to switch it off).
But it doesn't work. Any ideas why not?
Thanks very much for your help.
Regards
Stefan

Hello,
thanks for the answer, but it's not working as expected.
I thought if connection pooling is switched off that the connection is closed when the user logs off or navigates to a different iView (without backend connection).
This doesn't happen.
Am I wrong in my understanding?
Thanks
Stefan

RV180W loses port forwarding rules when switching WAN connections

We have a backup WAN connection in our office, but we switch this connection manually on our RV180W when the primary goes down. Our normal connection is ADSL with PPPoE, and the backup is Cable with DHCP.
However, we also have some port forwarding rules for our VoIP PBX (UDP port 5060) as well as SSH, and these rules seem to stop working completely when we switch our WAN connection to our cable connection. We can still surf the web from our workstations, but our incoming phone calls and SSH connections all cease to work completely. The problem does not persist after we've switched back to our normal ADSL connection.
This behaviour is completely bizarre and suggests that there's some kind of bug in the Cisco RV180W.

helm,
I'm sorry, I wasn't clear which IP address renewal I am speaking about.
I believe that the problem is caused when the router renews the WHS's local IP address (192.168...). My WAN IP address remains unchanged througout the tests I performed and the problems I experienced.
The very act of changing the local clients' lease time in the router's configuration causes the forwarding to be lost immediately. (I am gusessing that when the lease time is changed, the router immediately renews the lease and begins a new countdown.)
(In fact, I might go as far as to say it is a bug in the firmware, but I haven't done enough testing to nail it down.)
