Cisco Switching/Routing :: C2960 - Edit Vlan SNMP Group Context?
Feb 6, 2012
When using Cisco IOS c2960-lanbasek9-mz.122-50.SE3.bin we can delete line in SNMP group config with
no snmp-server group <group-name> v3 priv context vlan-<vlan-id>
without problems.
But, after upgrade on version c2960-lanbasek9-mz.122-58.SE2.bin there is output:
#####% Ambiguous command: "no snmp-server group <group-name> v3 priv context vlan-<vlan-id> "
It looks like some bug, but there is nothing in the bug toolkit.

Is it possible to use 1 or 2 of the 4 gigabit ethernet ports from one ACE straight into the other ACE for redundancy? So ACE_01 gig0/4 to ACE_02 gig0/4.If so, is it a case of just having the layer 3 config instead of trunking etc..Also - is it possible to create a context within the same vlan as the Admin context?

We have Cisco Cat4503 series L3 Switch and Cisco L2 2560 Series Switches, some of the users want to have a dynamic VLAN membership, and connecting with the network as mobile users,
can it possible and create dynamic VLAN for specific group of users.

I am trying to configerate static switchports on our nexus 5548 (nx-os 5.1(3)N1(1)) over snmp.The support-list url... states that the CISCO- VLAN- MEMBERSHIP- MIB is supported.I can read the information, but if i try to set vmVlan or vmVlanType i get the message: "SET failed. ("ip-address"). Information: Not Writable."I can use set_request in general (e.g. CISCO-CONFIG-COPY-MIB). how to set the vlan and vlan-type over snmp?

I want to know what is the different between IOS of the catalyst WS-C2960-48PST-S and the IOS of catalyset WS-C2960-48PST-L.a want to upgrad the IOS of a WS-C2960-48PST-S with the IOS of WS-C2960-48PST-L (because this reference has a LANBASE version of IOS).

I have a problem with adding a Cisco switch to the NMS (Smarts). When I start a discovery process from the snmp manager (Smarts NMS) it does resolve the ip address into the host name but once the discovery process is completed the device in question is not added in the list of managed devices. Attached is basic configuration.

I am very new to configuring ports on a switch. My boss usually does the port configurations but I am starting to learn some of the basic commands. The commands I know how to do are; close a port by typing config t, int gi0/port# and typing shut. I know how to enable a port, but how can I add info to a port or copy settings from one port to another?
We have some ports that are configured for 192.168 addresses but most are 10.128 addresses. I need to configure a certain port to be able to receive 192.168 addresses.

I have to add some new ACEs on a Critical production 6500 running CatOS.The documentation that I have seen so far explains how to create, commit and vlan map a VACL ... however I see no instructions or comments on best practices for editing VACLs.

I am setting up a new pair of ASA 5585's in a multi-context, active/active failover design. I cannot create management SSH connection to the contexts that are assigned to failover group 2. With all the security contexts that are assigned to failover group 1 I can SSH to the inside interface IP and login without a problem. When I try to do that to the group 2 contexts there is no response from the firewall at all, PuTTY just times out.
My firewalls are running version 8.2(4). The contexts seem to be functioning normally in all other respects.

what´s going on with an asa540 configure in multiple-context mode. I Have a cacti server on my lan and now I´m try to monitoring the interface with snmp. When I try to get this information returns the error message:
CISCOASA/CONTEXTA#

JUN 11 2013 01:52:01: %ASA-1-1-6021: Deny UDP reverve path check from 10.6.6.6 to IP_SRV_CACTI on interface inside
If I try to ping returns the same error:

We have a customer who uses about 20 x c2960's switches for access layer and 2 x c3560e for distribution layer. C2960's uses C2960-LANLITEK9-M , Version 12.2(58)SE1. Everything was working fine. Now we got information, that sometimes there are problems with connectivity. Customer tries to reach internet.

I am trying to configure RSPAN for one of my client. They have Server-Client VTP architecture. Voice Recording Server is connected to C4507. Agents are connected to C2960 and C3750. I got 2 sessions configured and the connectivity is a as follows:
1. Voice Recording Server-----C4507-----C2960-----C2960-----Agent IP Phones (Session 1)
2. Voice Recording Server-----C4507-----C3750-----Agent IP Phones (Session 2)
Recording works with Session-2 but not with Session-1. I understand the problem could be due to multiple reasons: 1.1. C2960 is working in client VTP mode so i cannot add remote span command under the vlan configuration. 1.2. C2960 has LANLITE IOS image which i am not sure if it supports Remote Span.

I have a C2960-24TT-L Switch with the following problem:When the Power Cord is plugged in the Switch, all switch indicator LEDs go on very briefly. Then SYST LED blinks very briefly, goes on steady and remains at this state without any indication at the console.Tried the reset by holding the MODE button while plugging in power but I still get no indication at the console. All is fine with console, meaning that if I take out the cable and plug it in another switch, then I see all that there is there to be seen.My question: Is the switch beyond repair or is there something that can be done to get the switch to run POST and boot at rommon so that I can reload SW and configs?

I have two WS-C2960-24TC-L Switch with Software Ver 12.2(25r)SEE6 with image c2960-lanbase-mz.122-35.SE5.bin and 12.2(25r)SEE1 with image c2960-lanbase-mz.122-25.SEE2.bin currently on it.
I want to enable SSH connections on the switches and believe I need to import the cryto image onto the switch. I would like to upgrade it to new version that can also support ssh connection but not sure which image to download from cisco. The switches are now live.
System image file is "flash:c2960-lanbase-mz.122-35.SE5/c2960-lanbase-mz.122-35.SE5.bin"
cisco WS-C2960-24TC-L (PowerPC405) processor (revision H0) with 61440K/4088K

I've got a C2960 (sw01) and a C2948. (sw02) The sw02 switch is trunked with sw01, and is meant to serve as an extension to the VLANs (1-4) that exist on sw01. It is trunking properly, however, how would I go about giving the sw02 an IP so that I can access it via SSH? Would I have to create a VLAN specifically on sw02 with an ip and switchport an interface to use it? I know that a VLAN can only have a single IP, but I'd like sw02 to have an IP on VLAN1 (192.168.1.0 subnet), is that possible?

I am not sure why the CRC and input errors are increasing in fastethernet port...This port is used as Intradomain cross connect to Data Center service provider for LAN extension between two Data Centers in different locations... The link is 100 MB. The switch port is directly connected to patch panel of DC provider and I believe they have some L3 switch or some other device that is providing LAN extension...

Yesterday I tried to install c2960-lanbasek9.mz.12.55.SE4.bin onto my router. When I changed the boot commands, I did not leave the 2nd option in there and the old firmware has an .ex3 extension. After trying to boot to this new image, we receive a looping error message that continues to reboot and go through the same process.Basically the error is "ERROR: firmware not supported by hardware"I have power cycled it a few times but durning bootup, I never see the ################## which would allow me to BREAK sequence and get into rommon. The device simply waits about 30-40 seconds after boot and goes right back to the looping reboot sequence and the error message. Is there any hyper term or putty settings to change on this?

I'm trying to configure the GigabitEthernet interface of the WS-C2960 switch to have a full duplex. Unfortunately, there is no option to configure this neither is the speed of that interface. But these options are present in FastEthernet ports. Is there a bug in SW version 12.2(35)SE5 that explains this abnormality?

I have an inquiry about a configuration I deploy in a C2960 switch. I have configured a ether channel with 8 ports, the load balanced method is source mac address. The bundling protocol is LACP.
I have found the ether channel is not balanced as I expect. One of the eight interfaces is congested.

Customer has a Catalyst WS-C2960-48PST-L. and in some ports we have VoIP phones with PoE company Aastra. If I use first config we have problem when phone boot up.
First config:
description tp-11-voip
switchport access vlan 250
switchport mode access
switchport voice vlan 201
switchport port-security maximum 2
switchport port-security(code )
The MAC shown here is from a voip Phone. After the phone boot up, the p, because it must boot first in vlan 250 (access vlan). On the port you can only see the MAC from vlan 201. With the second config the phone can boot without problems:
interface FastEthernet0/48
description tp-11-voip
switchport access vlan 250
switchport mode access
switchport voice vlan 201
is there a reason, why it is the problem with the first config on cat2960 ? The same first config works with an Cat2950 without problems.

Switch A is: WS-C2960-48TC-S
Switch B is: SG 300-10MP
Neither switch supports a similiar transceiver module. We are looking at transceiver GLC-SX-MM for Switch A, and MGBSX1 for Switch B all the Layer-1 information (SX / wavelength, Multi Mode, etc.) I am able to find out about the two transceivers seems to match, so would there be any issue by having these 2 "different" transceivers at either end?

A quick one because I'm scratching my head trying to figure the difference between the 2960 LAN Base and LAN Lite IOS installs. I want to put a 2960 into a site which has as layer 2 link on dark fiber taking it elsewhere. This part I'm not concerned about - the WS-C2960--24TC will do what I need without issue - but I don't know if I can get away with LAN Lite, or if I need LAN Base.
I basically need V LAN's with associated SVI's, and a routed link on the up link port (I don't care if it's a switch port with an associated SVI or a no switch port and IP address), but it's got to be able to run OSPF. Can I do this with LAN base on this series switch? Or do I need to go for a higher series (3560?). I *could* get away with static routes, but my boss is walking death on them unless I can 100% prove they're necessary, so I'd rather not right that fight!
