This 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.

Do I have to buy flexstack module and cables? If so where does the module go on the switch? If this switch cannot do this set up, any other switch I should look at.

View 1 Replies View RelatedWe 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.

View 2 Replies View RelatedOn 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.
I have two Cisco 48 port Catalyst 2960-S series SI. Instead of buying the pricy stack modules can I only use the SFP+cable to connect them as stack? which type of SFP+cable should I buy? do I need any license to use those SFP ports?

View 1 Replies View RelatedI 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.

Today in my rush to get home I plugged in a new 2960 stack and did a little bit of very basic configuration, but no passwords were set. I tried to telnet in and the message says that a password is required, but none is set. I tried the SDM as I hadn't turned it off yet and it is prompting me for a user/pass but I have no idea what to put in there. No console is available, it's a new office so no employees around either.

As per the attached diagram: How do I configure the 2 ports on the 3560 (Ports 6 & 7) and the connected ports on each of the 2960 switches (Port 25) to provide redundancy.
If the up link from Switch A dies then I need the traffic to flow through the trunk and utilize the up link on Switch B with minimal delay (milliseconds).
I need to configure a Cisco 2960 switch as a DHCP server. The current IP address will be on a different seed than the DHCP addresses. i.e.
Switch IP = 10.1.2.3, GW = 10.1.2.1, Subnet = 255.255.255.0
DHCP addresses would be 192.168.1.1 - 200, GW=???? (10.1.2.3?) and subnet would be 255.255.255.0
I am configuring a Cat 2960 port for connecting a VOIP phone, authenticated by MAB. On connecting the phone, I get the port authenticated and assigned to the correct VLAN, with LLDP-MED advertising the correct voice vlan. However, I then see no traffic from the phone on the switch. I can see the MAC address of the phone is learned in the right VLANs, but the mac address is showing as "Drop", which normally means the address is statically configured to be blocked. There is no static mac address table blocking configured on the switch.

How to change ip address in cisco 2960 series switch?
