2900

Unanswered Question
Jan 3rd, 2008

Dear all,

i've a few of 2900 catalyst switches due to a recently equipment refresh in my work place. when i try to connect to the new 2960 ttl, what ever equipments that is connected to the 2900 doesn't seem to join the network. the light at the cascading port blinks but it's as if there's no network. both switches have not been configured.

would upgrading the firmware for 2900 helps?

thank you.

The interfaces won't negotiate a trunk because the default switchport type is dynamic auto vs. the 3650's (dynamic desirable). Just set one port to dynamic desirable and you'll be good to go!

ex.

switch(config)#int fast0/12

switch(config-if)#switchport mode dynamic desirable
