Issue between two switches.
Switch1 is uplink switch (WS-C3524-XL),FastEthernet0/24 in vlan 1 by default, is connected to Switch2(WS-C2960-48TT-L) to Gi0/1.
When i put Gi0/1 in
interface GigabitEthernet0/1
switchport mode trunk
speed 100
end
it does not make any change , but when i put Switch1 port f0/24 into
switch port mode trunk i lost the connectivity.
i suspect issue in switch2 g0/1 port because when it is configured for trunk or in vlan1 i do not see any change.
vlan1 is management vlan .
pls suggest !!!

rohit,
Can you post the errors you mentioned?
Are all interfaces up?
please post a "show int status o" command n both interfaces?
Hopes you are testing connections from the vlan1. If not, Have all switches been added the vlans?

Both switch have same vlan database, issue is all the vlan are not communicating except vlan1.

Rohit,
I should use either "dot1q" or "ISL" on both switches. Seems you are using Vlan1 as a native vlan. So dot1q will let vlan1 go without tagging but ISL does. Let's check WS-C3524-XL.
please do "sh inter trunk" command.That will explore what is happening.

Thanks for you help, but issue has been fixed.
uplink switch port was not supporting truck.
After changing port it start working.
