I have a 2960 that bounced several times over the weekend and then appears to have lost its configuration. Using CDP from the backbone switch pulls up the information below. Is there any way for me to configure the downed switch from another switch on the network? I am trying to avoid having someone from the site try to find a console cable and a suitable computer with a serial port. [code]
View 2 RepliesI did the DHCP configuration for my CISCO 2960 switch but the clients are still not able to get the IPs.see the configuration below.

I've recently purchased a Cisco catalyst 2960S-24TS-L & setup 3 V LANS 10 (no current IP),20 (192.168.2.1) and 30 (192.168.3.1) to reflect the router V LAN configuration & ip information. When connecting my PC to the switch to test connectivity on (2.1 & 3.1) I'm unable to connect to the the net but can successfully ping GW (int FE0.20 & FE0.30) 192.168.2.1 & 3.1.
The router is an Cisco 1801 & it seems this is where the configuration issue is but I'm unable to figure out how to complete the setup. It has been quite awhile since I've configured a Cisco router.
Ive never had this router connected to a switch so all router switch ports are in the default VLAN1 (192.168.1.2), with FE0 disabled. In trying to get the switch to communicate with the router I made the following router config modifications.
FE0 enabled with subinterfaces configured
FE0.10-currently no ip
FE0.20-192.168.2.1/27
FE0.30-192.168.3.1/27
I have two issues I want to resolve:
1) I do not know what additional steps are required to allow 2.1.& 3.1 V LANs to access the net.
2) I want to disable VLAN1 if possible & use the network IP for VLAN10 (192.168.1.0). I'm unsure how to do this as any change on VLAN1 immediately breaks router access and the router reconfiguration becomes more complicated with changes to the FW ACL etc.
provide a sample Voice Vlan configuration for the Cisco 2960 POE switch to work with the Non-Cisco IP Phones?
Will these commands work? Vlan 2 is the new voice vlan, Vlan 1 is the data vlan.

I have a 24 port 2960-S that is not communicating with a 2960-LST that it is directly connected to over fiber. The link is up on the LST but will not come up on the -S. What command should I use to bring up this link? I have tried no shut from the (Config-if)# prompt.

I updated to 15.0(1)SE3 and everything seemed to be going well. Tried to log back in HTTP (have not set n IP yet since it is still at my house... DHCP seems to be working) and I get a user/password screen that says level_15_access and it won't let me in.
Attempts to log in terminal have been unsuccessful. I can log in my dell switch which I am replacing and my APC units terminal just fine using USB to serial and Ubuntu.
I tried cisco as a password, user and password, admin, administrator no luck.
What is the best way to resolve this, is there a sure fire windows serial program or settings I should use in linux (currently 9600,8,N,1) to connect? I have looked through manuals till I am blue in the face.
At a college we have Ciscos 2960 and are trying to setup VLAN tagging and also using RST or MST. The traffic on the jack should get tagged vlan 248.We were told by the college that Ciscos in the labs will not work with the Alcatel switch that provides access to the lab. That Alcatel is in Bridge 1x1 mode. The college will not change the configuration on the Alcatel.We got the Ciscos to do VLAN tagging and can get network access. However the spanning- tree is not read properly. Cisco does not properly read the Alcatel's RSTP (since the Alcatel is doing tagging on the BPDUs). It places the root of the spanning tree under vlan1 instead of vlan248.
The college strongly recommends HP Procurves and we are using that as test.The following is the configuration on the HP and it works with no effort (it reads the spanning-tree information as MST)We will end up getting HPs instead, if the Cisco cannot work with the Alcatels.
Using Cisco 2960 series switches (Have 8 . 2 stacks of 4) to replace 6 old switches. 4 old switches had IP ranges of 192.168.6.*** and all new switches have 10.1.*.* addresses. Core switch has 10.1. as well as 192.168 ip addresses but i need to configure one vlan (5?) to route to 192.168 address. PC's on 10. address taking a long time to access 192 range.
View 2 Replies View RelatedI'm fairly new at trying to create isolated network segments on Cisco switches. What I'm trying to do is have multiple isolated paths that originate from my v Sphere infrastructure travel through a layer 2 link, v LAN, up to a MLS, and ultimately out to to the internet through a firewall. Each sub net might ultimately have a number of hosts on it, but I don't think the make up of those hosts will matter here.
My initial thought was creating v LAN tagged port groups on v Switches on my v Sphere infrastructure. Physical connections will go from my ESXi hosts to the 2900 series Cisco switch connected to trunk ports. Both v LANs would be configured on the switch but not assigned to physical ports. The physical connection to the 3750 would also be a trunk port connection from the 2960. The 3750 would have SVI's created that are attached to VRFs that would control route traffic. This might be totally wrong but from what i've read it seems to be going down the correct path I think.
Two part question, is this the best way to go about designing this network? If so I seem to be really struggling with the SVI/VRF part. Every time I create an SVI all of my hosts on the 10.10.10.x network can ping them, regardless of which v LAN they're on.
I just cannot seem to isolate the 172 network.
We had core(4503), distribution(3750), and access switches(2960) in our environment. Currently we configured the clock manually in each switch, but a reboot of the switch resets the clock also. We are planning to make a single switch as a NTP servers and others are clients to synchronise the correct time even after a reboot of the access switches.

View 5 Replies View RelatedI have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
Does the Model "WS-C2960-24PC-L" Supports IP Routing or not?

It doesnt like my password, but I have only set 1 password (king) on this switch. I've configured 3 other switches with SSH and had no problem. Been trouble shooting for awhile and It'd be great if I could have a 2nd set of eyes take a peek, Also, my running config is attached.
I am setting up a new 2960-S switch and none of the recommended username and passwords combinations work. I have tried CIsco Cisco, <blank> cisco and various other permutations.
I have tried to reset the switch to factory defaults and it still doesn't work. The switch is currently connected to a 3560G and has been assigned an IP. If I try to access it from Network assistant it shows as unmanaged and I get prompted for a username and password.The switch is connected to another new 2960-S via a FlowStack module.
I was wondering if I can force catalyst 2960 to skip startup config stored in NVRAM and boot with no config everytime it is powered. I tried to find it on google and in cisco white papers but still no luck. I found only commands that begin with "set boot config-register ... ", but switch acts like it does not know these commands.

I am going to creat VLANs very 1st time therefore for test purpose I have following simple scnerio.I have created 2 VLANs , VLAN2 and VLAN3 on Cisco Catalyst 2960 series switch. Ports 1-12 is assigned to VLAN2 and Ports 13-24 are assiged to VLAN3. Now I have configured DHCP on Microsoft Server 2003 defining 2 scopes with following configurations.
Scope 1 for VLAN 2--- Range is 172.16.0.17 to 172.16.0.30 with subnet mask=255.255.255.240 . Server IP address 172.16.0.17
( Note: Address 172.16.0.17 is excluded from dhcp server Scope 1 and give to the MS server itself)
Scope 2 for VLAN 3----Range is 172.16.0.33 to 172.16.0.46 with subnet mask=255.255.255.240 .
Now in Cisco 2960 series switches, under Vlan 2 and Vlan 3, I have following configurations...
interface Vlan2
ip address 172.16.0.30 255.255.255.240
ip helper-address 172.16.0.17
interface Vlan3
ip address 172.16.0.46 255.255.255.240
ip helper-address 172.16.0.17
Now the problem is when i connect a client computer to any port from 1-12, It gets correct IP address from Scope 1 but when I connect a computer to any port from 13-24, it does not get the ip address.
Further I want to do inter VLAN comunication as well for that purpose i Have an ISR 2900 series router. What further configuration i will have to do on router for inter vlan communication.
I have a Catalyst 4006 switch in production and a spare switch of same model. I have to quickly copy the configuration from production switch to spare switch (both L2 and L3 configurations) How do I do that?
