How to Etherchannel between Cisco 2960G Switch and Sun using LACP?

snguyen

Level 1

Hello Everyone,

I have a Sun Server with two 1G ports and trying to connect with my Cisco 2960G on port G0/23 and G0/24 but I am having problem to ping between the Sun Server and Cisco 2960G Switches.  Please let me know how to fix this problem, also how do you change the Admin and Oper keys in the Cisco Switch to sync with Sun Server keys?

There is no error msg on the log.

Thank you for your help.

1-Cisco 2960G Switch configuration:

!

interface Port-channel1

switchport mode access

!

!

interface GigabitEthernet0/23

switchport mode access

channel-group 1 mode active

!

interface GigabitEthernet0/24

switchport mode access

channel-group 1 mode active

!

!
interface Vlan1
ip address 10.99.20.4 255.255.252.0
no ip route-cache

Hello,

Do you have to use LACP? Did you try mode on? Not sure about the second part of your question.

Thank you Fabienne,

Yes, I have to use LACP because Cisco interface with others mfg device.  If Cisco interface with Cisco then I don't have to.

The second question was How do you change admin and operation keys in the the Cisco 2960 (which commands)?

Everything is working now but I have to ask our Unix admin to change key in the Sun Server side.  Again is there a way to change keys in the Cisco 2960G switch (I know there is way to change key with 6500 switch)?

Thanks.
