Spanning tree - balanced without use vlan ?

Hi, i´m sorry if this is a classic question.
i have implemented rapid pvst like show in the image. The dotted lines are the alternative links. (image 1)
SwitchA# spanning-tree vlan 1 root primary
SwitchB# spanning-tree vlan 1 root secondary
I want to make a kind of balancing like image 2. But the problem is that i have vlan 100 (and other vlans) in side A and Side B.
So, if i make
SwitchB: spanning-tree vlan 100 root primary
SwitchA: spanning-tree vlan 100 root secondary
The SwB it change to primary for vlan 100.
But i want to the switchB be the primary for side A and secondary for side A. No matter the vlan. Is possible?
Thanks a lot!
IMAGE 1
IMAGE 2
PS: Later i will implement HSRP.

Hi, i know that is possible, but doing this the result is unbalanced for mi network. For example vlan 20 reside in all switches and vlan 21 reside in only one switch.
i want to the switchA be the primary for side A and secondary for side B. No matter the vlan. Like image 2.
I hope to be clear.
Thanks.

Can I disable spanning-tree in a vpc domain ?

i have two N7718s in a vpc domain and each have a vpc connection to 300+ TORs(non cisco switch).
each 7718 have 300+ trunk port and a trunk port carring 80 vlans . so the logical port number is 300*80 = 24000
the problem is n7k r-pvst logical ports limit is 16000,it causes the vpc primary 7718 ping latancy time exceed 1000ms
2 ways to solve this problem : use mst instead of rpvst or disable spanning-tree
if i use mst , the logical ports limit is 90000, the problem will appear one day
so i want to disable spanning-tree . 7718s' vpc link to TOR use lacp ,it will prevent some layer2 loops. can i do it?

I have the same problem. :)

"Peer-switch" command on vPC domain and spanning-tree priority interaction

Hi guy,
We have 2 N7K (N7KA and N7KB) which will be running vPC in hybird and pure vPC environment.
I have a question about the Hybird and pure vPC environment. With the "peer-switch" command enable, should i tune the spanning-tree priority to be the same for all the vlan running on vPC on both N7KA and N7KB? This way, when i enter the "sh spanning-tree vlan X(vPC vlan) detail" command on N7K, it will list both N7K announc itself as "We are the root of the spanning tree".Also the switch running spanning-tree with N7K vPC vlan (Hybird), will see both N7K has the same priority (4096), and it is not desirable for a spanning-tree environment. Therefore, i used the "spanning-tree pseudo-information" on N7KB to tune the spanning-tree priority to "8192" and the switch running spanning-tree with N7K will list N7KB has a priority of 8192(perfect).
However, I notice some strange "show" output on the switch running Port-channel with the N7KA and N7KB. The "Designated bridge" priority is flapping as show on the switch. It is constantly changing between "4096 and 8192" with the same vPC system wide mac address.
Entering the "sh spanning-tree vlan X detail" command repeatly on switch with port-channel toward N7KA and N7KB.
>>sh spanning-tree vlan 10 detail
Port 65 (Port-channel1) of VLAN10 is root forwarding
Port path cost 3, Port priority 128, Port Identifier 128.65.

We have a issue similar to this in our environment. I am trying to upgrade the existing 3750 stack router with 2 Nexus 5596 running VPC between them. For the transition I have planned to create a channel between 3750 stack and 5596's. Once this environment is set, my plan is to migrate all the access switches to N5k.
The issue is when I connect the 3750 port channel to both N5Ks, all the Vlans on 3750 started to flap. If I connect the port channel to only one N5K everything is normal; but when I connect the port channel to both N5K running VPC, vlans are flapping. Any idea what is going wrong here? Am I missing something?

Spanning tree question

I want to change the spanning tree root on several vlans on my network. My question is, will this cause STP to recalculate for the entire network, which can cause the network to slow down or will it only affect the vlans that I am changing? I want to make sure I am not going to impact anything on the network.

When executed properly, this will only affect the vlans that you wish to change. Use the folllowing command to change spanning tree prio on a vlan:
spanning-tree vlan xx priority 4096 (or a multiple of 4096 for less priority)
Be aware that there is always a risk of unexpected disruptions when you do this. The vlans that you change may still carry user traffic altough there are no users on it. If your topology and traffic flow are not exactly as you assume they are, more vlans may be affected. It is therefore not advisable to alter this setting during peak-hours.

Without using order by and connect by clause

hi all,
can i write a tree query without using start with clause and connect by clause
and
can i order the employee names in a select query without using order by clause
can those things are possible in select statement...

Those clauses are the means to do what you are asking. Why would you be looking for some other method?

SGE2010 switches, VLAN's and a blocked port in spanning-tree

Folks,
I have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.
Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW
Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.
As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
I have attached an image with a diagram of our current set up.
Any help/advice would be much appreciated.

Tom,
I remember our conversation a few weeks ago. I did not get a chance to have a go at MSTP, mainly because I have no expierence with it, and looking at the configuration properities, it looks a little daunting.
It has also been a very busy few weeks with the deployment of 200+ phones across several sites, and the system is functioning great with out the LAG trunk, I am just trying to plan for the future.
I made a few postings a few weeks ago, one here and one on the Cisco forums on reddit, and a user there gave me some advice I have been unable to make work (I think it's just wrong), but I would love to go this route if it is in fact possible.
Here is the thread : http://www.reddit.com/r/Cisco/comments/x91tc/vlan_trunks_spanning_tree_and_a_port_blocked/c5kskch
This user implies it's possible to block a VLAN across the LAG which would end the logical loop problems.
It looks like his advice is to make the LAG into a trunk, and then block specific VLAN's from transiting it, but in trunk mode, I can't assign it an IP, so I am sorta wondering how exactly you transport packets across it.
Can you confirm that his advice is in fact incorrect?
If MSTP is my only route, then I suppose it's time to dig into the docs and see If I cant get it up and running.

Spanning Tree MST per Vlan, best practice

Hi Community.
I did the following MST Spanning Tree Config
spanning-tree mst configuration
name xxxxxxx
revision1
instance 1 vlan 1, 10-20, 25, 30
So I added every Vlan to the config which we use. But every time when I add one more vlan to the config the whole network get a little outage.
I see lots of MAC Flaps on ports with two Server links and the outage is for some seconds.
Is it a better practice to add all possible Vlans to the config. So I do the config like that:
instance 1 vlan 1-4096
What you think.
Best Regards patrick

Hi,
So I added every Vlan to the config which we use. But every time when I add one more vlan to the config the whole network get a little outage.
Correct, that is normal behavior with MST.
I would just add "instance 1 vlan 1-4094" this way there is no outage when you bring up a new vlan.

Spanning tree for VLANS

Hi,
I need an answer to this puzzling scenerio i have been asked to work with.I have two vlans with about 10 switches on each end and there is a link switch that has a connection to both sides of the VLAN. I have been asked to create a singular spanning tree for the entire scenerio. how can i go about this.
please i am awaiting the opinions of anyone knowledgable in this line. thanks.

Hi, I agree you can config MST on your router to reduce the number of spanning tree instances runing on the switch from one per vlan. You will have to map your vlan range to the MST, useful CLI commands are
spanning-tree mode mst
spanning-tree mst configuration
name (name)
revision( revision number)
instance (number) vlan (vlan range)
check your config using
show spanning-tree mst configuration.
Hope thsi will hlep you get started.

The spanning-tree add strange value when I create new Vlans

Hi,
On all switchs access, the spanning-tree add strange value when I create new Vlans from Distrib Layer,
and no association is created with any interface with spanning-tree vlan 700, see below in this exemple,
until I reboot the switch.
somebody already saw this values ?

Venki,
The ORA-00942 is okay because there is no existing object. But what stuck me is the ORA-01921 error which may indicate that this might not be a new database.
CREATE ROLE exp_full_database
ERROR at line 1:
ORA-01921: role name 'EXP_FULL_DATABASE' conflicts with another user or role name
CREATE ROLE imp_full_database
ERROR at line 1:
ORA-01921: role name 'IMP_FULL_DATABASE' conflicts with another user or role name
Are there any existing databases on this server? Have you tried to create it on other machine?I searched on Metalink too and found Doc ID: 237486.1 ORA-29807 Signalled While Creating Database using DBCA which say that eroror could be ignored. You may want to review that as well.

E100 & E1000 Spanning tree and VLAN reuse

I have a situations where I have two e series cards configured as single card ether-switches in the same chassis. One is an E100 and the other is an E1000. I have spanning tree enabled on all the transport circuit built to these cards. There is no STS connectivity between these cards.
I am reusing a few VLANs between the cards and the cards appear to be sharing spanning tree topology information. Has anyone had similar experiences reusing VLANs and discovered a work around for this? The 15454 documentation is not very descriptive of this situation and lacks detailed STP info as on would expect to be accessible from a Cisco switch.
Thanks,
Ken

I'm not so sure that singlecard/multicard mode has anything to do with STP on E-Series cards. From the book Optical Network Design and Implementation:
"It is important to remember that in the case of the E-Series cards, the Timing and Control 2 (TCC2) common card actually runs the spanning-tree engine with a single instance of STP per node. Each E-Series card plugged into the chassis maintains only a copy of its Layer 2 forwarding table. In the case of ML-Series cards, however, the individual cards maintain copies of the Layer 2 forwarding table and they run an instance of STP." ... "From an STP perspective, however, the entire ONS node is perceived as a single bridge, even though it might contain multiple E-Series cards. For ML-Series cards, however, each card is accounted for as a discrete bridge, and STP uses each and every ML-Series card for its STP computation."

Spanning-tree vlan 1002-1005

Hi,
I have noticed that two of my switches has "spanning-tree vlan 1002-1005" in my running configuration. Since we are not using those vlans, I was thinking of removing it from our running configuration by doing "no spanning-tree vlan 1002-1005". Is that possible? Would there be any issues should I remove it?

VLANs 1002-1005 are special default VLANs for Token Ring and FDDI. If you do not have those tachnologies, then you are probably not using those VLANs. Do the VLANs exist in the VTPS domain? If not, you should be able to get rid of them altogether.
When you do a "show vlan 1002" on those switches, do you see any active ports? NOte that some switches allow you to clear these VLANs from a trunk, and some do not.

Cisco Noob - Layer 3 Routing / VLAN / Spanning Tree

Hi All ...
I need some pointers on which commands / settings and where, I know what I want to achieve but the things I am trying seem to be 'mutually exclusive' - either that or i'm missing something - I am not a Cisco IOS expert but I know my way around a network.
Take 3 3560 switches in Layer 3 mode, there is a 'local' fibre spanning tree ring serving mulriple switches on each, each ring is it's own IP segment / VLAN. There is then a trunk between each switch on which I want to establish a load sharing / spanning tree circuit i.e.
SW1 hosts VLAN 2 via copper on fa0/1 -12, ip address 10.10.2.254
SW1 hosts VLAN 3 via a fibre spanning tree circuit on G0/1 & G0/2, dhcp 10.10.3.0/24, trunk 1 on G0/3 and trunk 2 on G0/4
SW1 hosts VLAN 10, ip address 10.10.10.1 (trunks 1 and 2 have no IP address but are members of VLAN 10)
SW2 hosts VLAN 4 via a fibre spanning tree circuit on G0/1 & G0/2, dhcp 10.10.4.0/24, trunk 1 on G0/3 and trunk 2 on G0/4
SW2 hosts VLAN 10, ip address 10.10.10.2 (trunks 1 and 2 have no IP address but are members of VLAN 10)
SW3 hosts VLAN 5 via a fibre spanning tree circuit on G0/1 & G0/2, dhcp 10.10.5.0/24, trunk 1 on G0/3 and trunk 2 on G0/4
SW3 hosts VLAN 10, ip address 10.10.10.3 (trunks 1 and 2 have no IP address but are members of VLAN 10)
SW1 G0/3 is a SMF trunk to SW2 G0/3
SW1 G0/4 is a SMF trunk to SW3 G0/3
SW2 G0/4 is a SMF trunk to SW3 G0/4
The trunks are configured as "trunk encapsulation dot1q", ip routing is enabled.
I can get the trunks working OK - but I can't seem to get routing to work across them - if I define an interface on SW1 with an IP set in SW3 the switch complains so it can clearly see it so which command have I missed.
All VLAN's are part of the same domain, each VLAN has it's own DHCP hosted on it's hosting switch. The VLAN ip address is excluded from DHCP and is the default gateway for each VLAN.
All VLAN's must be able to reach VLAN2 (contains SQL servers and DNS, Time etc etc), the VLAN's are working, DHCP etc is all working - but I can't get anything other than VLAN 10 IP's to talk across the trunks - I've tried adding spanning-tree vlan 2,3,4,5,10 but this hasn't worked, the ip route-map shows nothing, if you show spanning-tree the trunk ports do show up as an interface for all VLAN's - and yet no traffic passes across them - show route displays nothing. I tried adding ip route 10.10.*.0 255.255.255.0 10.10.2.254 (where 10.10.2.254 is the ip address of VLAN 2) but that's done nothing.
I have tried various combinations - unsuccessful so far - I need the trunks to be not only fault tolerant but load sharing which kind of negates fixing IP's on them - or does it ?? - what am I missing ?
(switches are all running IP services IOS)

Hi John ,, here is the sh ip route and sh ip eigrp from all three.
The ip address I'm trying to reach from SW1, SW2 is 10.10.2.253 - the DNS server - the server is available and connected to a copper port designated and assigned to VLAN 2 (which has the root ip of 10.10.2.254) dhcp is not enabled for VLAN 2.
I can ping the DNS box from VLAN 5 (same switch as VLAN 2).
The copper ports on the SW1 and SW2 boxes refuse to 'come up' - they remain shutdown no matter what. I haven't yet configured VLAN 10 ....
(NOTE - these switches are on the bench right now - I intend to ge tthe config sorted / tested and verified before they go into production)

PPS : I'm using ports Gi0/1 and Gi0/2 for now - I removed these from DB5-LAN and can now 'ping' from SW1 but not from SW2 - but the local copper is still dead on SW1 and SW2

Sniffing vlan without using monitor session

Hello,
I am trying to configure sniffing on vlan without using monitor session on 3550 - 122-25.SEB. My idea was to put static mac mapping for all the mac addresses in the vlan to one port where to put IDS sniffing interface. Unfortunately the switch doesn't accept static mapping for mac address that he already knows via dynamic mapping on one and the same vlan. If I first shut down the port where the source device is located then I can put static mapping but after enabeling the port again the switch doesn't lear the dynamic mac. Is there any other way to redirect traffic ? I am thinking also if I can disable mac address learning on this vlan ->turning the switch in to hub for this vlan ?

Your vlan also needs to be configured for remote-span:
vlan 35
remote-span
I would keep the filter attached, if the frame is not "good" it can't do any harm on the destination-system. It typically won't even get there.
And make sure that you don't have too much span-traffic on the interswitch-links and the destination-link.

Spanning tree - balanced without use vlan ?
