SG 300-52 52-Port Gigabit Managed Switch

Hi Gentlemen,
We have recently purchased SG 300-52Port Cisco Switch to support our Network but they constantly having some bizarre issues or I assume bugs, i.e. we cannot Telnet nor SSH to the switch now, whereas we were able to SSH before, we have set them up for Remote Log Services to get some syslogs and reports but no report have been generated nor logs,
I have done some testing through Wireshark and there are absolutely no reports / logs.
We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,
SG 300-52 Port Gigabit Managed Switch
Firmware Version (Active Image ) : 1.1.1.8
Firmware Version (Non-active ) : 1.1.0.73
Boot Version : 1.0.0.4
It would be appreciated if someone could shed some light so that we could fix these issues.
Thanks.

Yes, i am able to log into Web GUI,
I have had some serious issues before with set up/add different VLANs but we somehow make it work even though i am not optimistic...
Other problem that is now pending is setup Remote Log Services to get some syslogs.. it doesn’t generate anything no logs no reports ...
I am going to backup it up / reset /update the firmware again and see how it works.
Let me know if you have any suggestion.
Thanks.

SG 300-28 28-Port Gigabit Managed Switch -Lan connectivity issues

Hello,
Our office lan running on 2 * SG 300-28 28-Port Gigabit Managed Switch.
PID VID:SRW2024-K9 V01
Firmware Version (Active Image):1.0.0.27
The users are seeing there connection to fileservers(mapped network drives) slowing down over the period.
We have to re-boot the offending switch to get the normal traffic back.
I have raised a ticket with cisco small business people and they said to upgrade the firmware to latest version.
But I am wondering why I need to upgrade this switch as the other switch which also brought at the same time with the same spec have no such issues.
Even if I decided to upgrade the firmware, they have recommended that I need to reset the switch to factory settings and try to put the previous configuration manually which is a worry for me.
I have logged on to the web console and I have found out, I can use TFTP or HTTP to backup the config,how do I use those services and what parameters i need to pass those to work, does using that functionality can rollback the switch to previous running configuration?
PS: Both the switch have connected together using a FC trunk with link aggregation eanbled.So how do I get all those settings back if I upgrade/rollback?
I just have to come up with some solution as it is affecting the business, so any help would be much appreciated.
Please see the attachment and let me know if any other info needed?
Thanks in advance,
Regards

Hi,
Please see the difference between the connected switches configuration.
Maybe the vlan 10 and 30 has been created wrongly.
Please see the config for both the switches and give me some advice/suggestions.
I really appreciate that.

SG300-28 28-Port Gigabit Managed Switch

I've forgotten username & password of SG300-28 28-Port Gigabit Managed Switch. Is there any to recover them? but I don't want to lose configurations.

Hi Anton,
You can access boot menu and choose password recovery but this option is only accessible via serial console and after you see Cisco logo hit ESC button once.
Once you choose password recovery current password will be ignored during this current session only so the first thing you need to do is to change and save new password. You can use CLI for this:
switch(config)#username cisco password cisco
switch(config)#exit
switch#wr
and you should be ready to go :-)

Cisco SG300-52 52-Port Gigabit Managed Switch losing VLAN-Port Membership

Hello
We have some cisco switches in use and we're facing some problems everytime the switch loses Power.
After a reboot the port/vlan membership is lost, so are other settings recently made (like SSH access allowed, etc.).
The settings made up a year ago like the IPs, password, etc. remain untouched.
Upgrading the Firmware, Saving the Configs, etc. didn't solve the problem.
Is this a known issue? Anyone facing the same problem?
Bye and thanks for the help.
Viktor

Cisco 5 port and 8 port gigabit unmanaged switches

I am looking for 5 port and 8 port gigabit unmanaged switches in Cisco. Please provide the BoM for the same. As per my understanding the following switches can suffice the requirement (SG100D-05 and SG100D-080) however I am not sure about the DC power, whether they can be used in normal AC environments.

The SG100D-05 and SG100D-08 are too small and their power requirements are too low to justify building an AC power supply into them like the larger SGx00 switches have, so they are wired to accept DC power and use an external power adapter (included) for connection to an AC environment.
There are really no optional components to these devices, so the BOM would be as follows:
5-port SG100D swich: SG100D-05
8-port SG100D swich: SG100D-08

CISCO SG200-50 Port Gigabit Smart Switch (VTP Support)

Does CISCO SG200-50 Port Gigabit Smart Switch provide support for VTP or Not. If not how we can make it a VTP client and how it will forward its VLAN information to VTP Server in VTP Domain in which it is connected.
Thanks

Hi Jay,
I am not very sure if this is the correct location to find the MTU, but you may check the following link:-

Link srw2048 and linksys 8 port gigabit smart switch linking together

Hi all,
I would like to link my srw2048 in the my celler to the linksys 8port switch i have in the living room so my son can have lan parties. how would i configure this and will i need to make a crossover cable?
Thanks in advance for any advice

I don't see the need of configuring your SRW2048 switch for you to be able to connect your 8 port gigabit switch. Since these switches were both smart switch you can use either crossover or straight through cable for them to communicate with each other.

CLI support for Cisco SG100D-05 5-Port Gigabit Desktop Switch

I would like to know if the SG100D series of switches support the CLI? If not what are the series of switches supported by the CLI.
I am looking for an application where I need to tell which device is connected to which port on a switch. Hence I am looking at this option where I can run a script and use CLI to output the MAC id of devices connected on each port.
Thanks!

Hi Yiu Kay Lee,
Thank you for sending me this document. It was very helpful. But I cannot understand one thing about it. Is it possible to extract the results from the CLI by passing a command via a script e.g. Python and get the results of it into Python?
For e.g.
************Python script ******************
>>print("send command to 200 series Cisco switch")
>> results = show mac-addr-table
>> print results
Please let me know if such interfacing with the CLI is possible or not?
Thanks

Management port for management switch(2960x) / IP default-gateway for L2 management switch

1)
I am going to connect all mgmt ports of server to this access switch (L2; 2960x) like below. Then I have a management port in 2960x (FastEthernet / L3 port). As you can see below, even though one of Core switch is down, I am able to access through the other Core switch for mgmt SW. Do I need this FastEthernet port of 2960X?
Core Pri ------- Core Sec   (Core Pri 192.168.1.2 / Sec 192.168.1.3 / HSRP VIP 192.168.1.1)
            mgmt SW ----- (FastEthernet0) ------ Goes to where? I don't have RAS (Remote Access Server)
                  |
                  |
      servers' mgmt ports
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-2_55_se/configuration/guide/scg_2960/swint.html#wp2220949
2) From server side, server put default gateway (192.168.0.1) so if destination is not known, it dumps all to default gateway. This is L3. I understand this. What about L2 default gateway from switch itself? The L2 access switch supports "ip default-gateway" command. I know that without this command still servers do not have any problems to connect to network. Then this command is for switch (2960x) itself? i.e I log into the switch and ping google.com then switch will try to resolve through DNS, but if DNS is not set up in the switch, it sends all traffic to "ip default-gateway"? Is it right?
3) If L2 (Access) switch has multiple data vlans and mgmt vlan (10.0.0.0/24 10.0.10.0/24 192.168.0.1). Then what will be the "ip default-gateway" for this switch?
Thanks for your time and knowledge.
======================== Reference from Cisco regarding ip default-gateway --------------------------------------
How to configure the ip default-gateway command on a Cisco 3550 series switch
VERSION 2
Resolution
To define a default gateway when IP routing is disabled, issue the ip default-gateway global configuration command. Then, enter the IP address of the next-hop router interface that is directly connected to the switch where a default gateway is being configured.
The default gateway receives IP packets with unresolved destination IP addresses from the switch. Once the default gateway is configured, the switch has connectivity to the remote networks with which a host needs to communicate.
Note: When the switch is configured to route with IP, it does not need to have a default gateway set.
For more information, refer to Assigning the Switch IP Address and Default Gateway.

Sb Sg300-10mp 10 Port Gigabit Poe Switch

Good afternoon,
Really need some assistance with this switch please.
When it's switched on it keeps going into a boot cycle. It's never worked but due to reporting it outside the accepted DOA timescale we are unable to return the unit,
Please could someone advise what I need to do?
Thank you in advance,
Amanda

Hi Amanda,
Sure does sound like a real problem.
But the switch has a tremendous warranty and support is free for products under service contract or warranty.
If you would be so kind as to contact the good folks at the Small Business Support Center (SBSC), they will either help fix the product or allow for RMA of the unit. their contact details are on the second URL below.
A SBSC technician will ask for a Cisco Connection online (CCO) ID, if you don't have one, go to the following URL to create one. https://tools.cisco.com/RPF/register/register.do This allows the the technicians to have contact details for you and for you to manage your service requests online at Cisco if that is what you want to do..

I am trying to use the SRW2024P Switch to setup a converged lab, with 7970, 7960g, and CCM. How do I set this switch up to setup VLANs and QoS/CoS/ToS to prioritize voice, video, and data in that order (perhaps data to use the defualt VLAN)?

Hi Amanda,
Sure does sound like a real problem.
But the switch has a tremendous warranty and support is free for products under service contract or warranty.
If you would be so kind as to contact the good folks at the Small Business Support Center (SBSC), they will either help fix the product or allow for RMA of the unit. their contact details are on the second URL below.
A SBSC technician will ask for a Cisco Connection online (CCO) ID, if you don't have one, go to the following URL to create one. https://tools.cisco.com/RPF/register/register.do This allows the the technicians to have contact details for you and for you to manage your service requests online at Cisco if that is what you want to do..

SG 200-18 18-Port Gigabit Smart Switch VLAN Setup Help Required

Small Network in my home using Cisco SG 200-18 also have Meraki MX60 Router.
2 of my Windows 2008 Server have Dual network adapters.
Need to put the second network adapter on another subnet.
My primary network is 10.2.8.x/22 10.2.8.1 is Gateway 255.255.252.0 is the subnet
New network is 10.1.8.x/22 Gateway is 10.1.8.1 Subnet 255.255.252.0
I need both networks to be able to talk to each other.
On one server I have both network adapters configured properly
My Meraki MX60 is configured with a VLAN of 1018 MXIP 10.1.8.1 one LAN port on the Meraki MX60 we tested and made it on the new VLAN
If I plug the second network adapter from my test server into the Meraki MX60 Lan Port and it all works from my pc on 10.2.1.x I can ping 10.1.8.1 which is the Meraki MX60 and I can ping 10.1.8.23 which is the test server.
My PC (10.2.8.99) can ping 10.1.8.23 also
Now for my Question
When I plug my Test Server second network adapter into port 13, 14 15 or 16 of the SG 200 I can not:
1. from my pc (10.2.8.99) ping 10.1.8.23
2. From the Meraki (10.2.8.1) I can not ping 10.1.8.23
3. From the Test server (10.1.8.23) can not ping 10.1.8.1
How do I configure the SG200 correctly?
I created a VLAN named 1018 (See the attached screen images)
How does my config look?
What am I missing????
Thanks in advance

Hi,
If I understand correctly you are trying to do inter-vlan routing, for packest to pass from one vlan/subnet to another it must be routed, than can be done by using a layer 3 switch ( the most optimal way ) or by using a router with a layer 2 witch, if you are using a router the router must have an interface in each vlan, you can also use sub-interfaces if the router you are using supports it. Another thing I noticed on your switch is that your ports are configured as trunks, this may not work well unless you know exactly what you are doing and you have a specific need.

SG200-26 26-Port Gigabit Smart Switch - MTU settings

SG200-26 26-Port, firmware 1.3.7.18
I have MTU mismatch on the network and the last device that can be responsible for the mismatch is my Cisco SG200-26. I was looking long and hard for where I can at least check what is the value of MTU on the switch but I can't find it. Ideally I would like to know not only where to check it but also where to change it. Can you please help?
Many thanks,
Jay

Hi Jay,
I am not very sure if this is the correct location to find the MTU, but you may check the following link:-

Let me know if this helps.

Never mind.
While at my desktop machine, I absentmindedly configured my network preferences for PPPOE, instead of leaving it to the router.
Once I adjusted my desktop machine for DHCP, all was well....

SG500-52P 52-Port Gigabit PoE Stackable Managed Switch Stack

Have created a stack with a SG500-52P 52-Port Gigabit PoE Stackable Managed Switch and a SG500-28P 28-Port Gigabit PoE Stackable Managed Switch.
All seems fine, but my query is the SG500-52P 52-Port Gigabit PoE Stackable Managed Switch is showing has Master and the SG500-28P 28-Port Gigabit PoE Stackable Managed Switch is showing as a Backup, should this be a Slave? Have a got the link cable wrong?

Nope. You're all good.
In an SG500 stack, there are three roles: master, backup and slave. The master currently holds the management role of the stack. The backup is the switch that will take over the management role if the master fails. Slaves are remaining stack members. As long as the master is active, the backup will essentially function as a slave.
If you only have two switches, there will be a master and a backup with no slaves at all.
