I have an issue with a trunk between a catalyst 2960 running iso 12.4, and an SSG 320 from juniper.
the juniper device is connected via a trunk to the cisco on the port fastethernet 0/1 configured as below :
switchport mode trunk
switchport trunk allowed vlan 10,11
there is a windows workstation connected to the port 0/2 with the config below :
switchport mode access
switchport access vlan 10
but the thing is that as I try to send a ping from the juniper with a size bigger than 1468 bytes, it looks like the ping is dropped by the cisco.
I also cannot send big pings from the pc workstation, unless I set the mtu manually to 1496.
how can I set the cisco to accept the traffic between the juniper and the pc ?
