Cisco Switching/Routing :: Can't Connect To Console On 3750X Stack Members
Oct 23, 2012I have a 3750X stack of 6 switches, I have a terminal server console server plugged into the console ports of all 6 switches. I am having a strange issue where I can connect to the master via the console, get a login prompt then I can log in, but when I try and connect to any of the members then I get a prompt "Press RETURN to get started" When I push return, it just loops back to the same prompt again:
switch-6 con0 is now available
Press RETURN to get started.
switch-6 con0 is now available
Press RETURN to get started.
I can connect to the stack via SSH fine etc. I am running 15.0(1)SE2. The stack is configured for TACACS+ auth via Cisco ACS.

Cisco Switching/Routing :: Port-Channel Members On Different 3750x Stack Members?
Mar 14, 2012i have a VSS core that has 4 downstream links to 4 stacked switches. I connected each of the 4 links to different switch in the switch stack. I then created a port-channel that combines all the links from each switch. Is there any issues associated with this setup?

Oct 23, 2012I have a set-up with multiple C2960 and C3750 switches. All these devices are being managed remotely. So basically I login to C2901, which is used as a Terminal Server, and reverse SSH to the console of each device. That's - I have assigned an IP to each port of the terminal server so that I can SSH directly to the desired device through via the mapped IP.
Now, recently I had to restart couple of switches - one C2960 and C3750. I initiated the reboot via console connection remotely. I could see the device logs for some time and then the logs stopped and there was no reaction from the console irrespective of any command I tried to enter.
I tried resetting the line on the terminal server, but that didn't work.
Now when I try to SSH the IP mapped to console of that particular device - i dont get any login prompt and there is no effect on device after giving any command. Although i can see the logs on the console session - but cant do anything.
I have a second way of connecting the device via inband- management, and checked the device config found it correct. It is same as other devices which are working correctly.
Both C3750 and C2960 are behaving exactly same - can see logs on console but see effect of even pressing enter - not getting login prompt as well.
Cisco Switching/Routing :: 2960S How To Upgrade Stack / Then Reboot Members One By One
May 15, 2013I have 2 Catalyst 2960S-switches configured in a stack. The uplink is configured as a cross-stack etherchannel. Now I want to upgrade the stack with a minimum of downtime for the connected hosts. The hosts are connected to the stack via cross-stack etherchannels. So my question is: How can I upgrade the stack and reboot the members with a minimum of downtime? If I use the archive download-sw command with the /reload-option, the stack is reloaded and the result will be downtime for the hosts while th stack is reloading. Is it possible to upgrade the stack and then reboot the members one by one in a controlled manner?

Cisco Switching/Routing :: Cannot Administer Catalyst 2960 Switch Via Console
Feb 20, 2013I want to configure my switch via console cable, the switch boots up normally, and there are no configurations present on the switch. However, anything I type does not appear on the terminal client. I used several terminal clients (TeraTerm, PuTTY, HyperTerminal), all latest versions as well as different PCs. I even forced the switch to rommon mode, still, anything I type does not appear on the terminal client.
Here's the output of TeraTerm:

May 20, 2013This is probably a dumb question, but I have read the 2960 stack administration guide and it does not explain how to configure the stack IP address. It says several times that the stack can be managed from the stack IP address, and that the stack IP address is a system-level configuration item. But it never explains how to configure the stack IP address.

Mar 25, 2013We have a pair of WS-C3750X-24T-S in a stack and four WS-C2960S-48TS-L in a stack of their own. There is not really anything too fancy configured (no special VLAN configuration/trunks or etc.) but the 3750 do have two ports configured as L3 for routing. We are not trying to use those ports for EtherChannel. These devices are running IOS 12.2(55)SE3 Essentially we are attempting to make an EtherChannel group using port 48 on all four of the 2960's in their stack (four ports). On the 3750 we will configure an EtherChannel group using port 23 and 24 on both switches (four ports). We then connect them up to form a four member EtherChannel.The ports on both ends are configured as mode ON and they are all 1Gb ports. I elected mode on because I understand at least one of the EtherChannel protocols will not work cross stack. What I would like to ask is whether the above configuration is possible or are we hitting some sort of limitation of EtherChannel cross stack, etc..? I cannot find anything to suggest this configration is invalid, but thought I would ask to see if I missed something in the EtherChannel articles.

Mar 7, 2013On first floor, I have two stack switches and each stack has got 4 switches. they all are working fine.Now the client would like to add one more stack on the 2nd floor. But the second floor switches are different when compared to the 1st floor switches.
can you have differnt IOS among different stacks. I knew in a stack we need all the switches should have same IOS version. But in between two stacks to communicate do we need same IOS or they can be on differnet IOS?
1st floor switches have 15.0 version and 2nd floor new switches has 12.2.58. Is this ok ?
1st floor switches are 3500 series ( Note: only one one Vlan 20 we are using on the both stack switches and we would like add same Vlan 20 on to the new stack)
2nd floor switches aew 2 catalyst 2960 switches.
Note: on the second floor switches one is 24 port switch and the other one is 48 port switch. so can i make them as a stack?
We have already done cabling from 1st floor to second floor. So no problem with that at all.

Cisco Switching/Routing :: Unable To Console / Ssh To 6513
Aug 9, 2012I have a 6513 with redundant sup 720-3B's that I cannot get onto. In short, one of the power supplies failed, it still passes traffic but I can't console or ssh to the box. Other than the two sup 720's, I have a 4 port 10gig card, a 16 port GBIC Card and an IDS module. I have tried removing the 10Gig, IDS and one of the sup's but still don't get anything on the console. I have rebooted the entire chassis and don't get anything on my console while booting. I have tried changing the speed of my terminal to every setting available incase someone has changed it at some stage but to no avail. I have tried swapping sup's, using only one at a time in the chassis but not getting anything. Is there anything else I can try to get onto this chassis? The power supply is a 3000w with a 32amp input. The failed power supply had tripped a switch, when i brought it back up, the power supply came out but the output failed LED is on. My #questions are, is there anything else I can do to try get onto the console, and is the power supply goosed when the RED LED is lit? I have reseated the power supply also but the same result.

Cisco Switching/Routing :: 2960 / ME 3600 - Stack Switches Are Good Solution For Resilience Of Huge Network
May 8, 2012I have a question for Cisco Cat.2960-s Flex Stack switches which are installing on our sties. Two of 2960-s Stack switches as access switch and two of Cisco ME 3600X Series as distribution layer switches are to be installed in our sites. In case of two stack switches, One is will be a Master and the other one will be a member logically, as you know. So, if the master fails, the other one automatically becomes the stack master following a well-documented election process.
Now, it is my question. How long takes to be a stack master from a member switch ? I cant find it on white paper of Cat.2960-s flex stack .
And also, I heard that sometimes a member switches don't election process when the master fails as a result, all stack members become
a panic. Is that really right ? In addition, I heard that the stack switches have many troubleshooting points than stand alone switches.
I really wanna know if the stack switches are good solution for resilience of huge network site. I'm waiting an answer from those who have experience of maintenance or installation.
