RE: 3750 stack problem?

Rodrigo,

What version of code are you running? What is the output from the following commands:

show switch stack-ring speed

Stack Ring Speed : 32G
Stack Ring Configuration: Full
Stack Ring Protocol : StackWise

show switch stack-ports
  Switch # Port 1 Port 2
  -------- ------ ------
    1 Ok Ok
    2 Ok Ok
    3 Ok Ok
    4 Ok Ok
    5 Ok Ok

show switch stack-ring activity

Sw Frames sent to stack ring (approximate)
------------------------------------------------
1 3054728688
2 2967790152
3 1725338565
4 1717715997
5 1996841958
6 2330025942
7 1937254349
8 1132789960
9 1229063481

Total frames sent to stack ring : 18091549092

This is from a 9 switch stack, as you can see none of the values are negative. To answer your question though, it shows the frame count between stack members.

Subject: 3750 stack problem?

Guys,

I don4t find about this in CISCO documentation:

- What does the command switch stack-ring activity show?

I have had problems of performance (slow access of stations and servers) in
this network with 4 switches 3750 in stack.

The 4 switches 3750 in stack are the CORE of this network.

Can does this command show me something?

Can you translate it to me? Why is it negative in switch 2 and 3?

Can I show a problem below? Can you suggest another command to find some
problem?

=============================================

3750-A# sh switch stack-ring activity

Switch Frames sent to stack ring (approximate)

------------------------------------------------

1 1731761798

2 -1942640275

3 - 959699416

4 28835091

Total frames sent to stack ring : -1141742802

Note: these counts do not include frames sent to the ring

by certain output features, such as output SPAN and output

ACLs.

Thanks
