Hi all,
I have two switches connected by trunk
First switch:
Catalyst 4000 L3 Switch ,Version 12.2(25)EWA3 image file is "bootflash:cat4000-i5s-mz.122-25.EWA3.bin"
And
Second switch:
WS-C3750-48P, Version 12.2(50)SE3, image C3750-IPBASE-M
All the devices connected to C3750 switch not showing in arp table in this switch, but showing in Catalyst 4000 arp table. I can see in the switch C3750 arp table only for the up link IPs.
This is the trunk config in both sides:
Catalyst4000#sh run int Gi3/2
Building configuration...
Current configuration : 199 bytes
!
interface GigabitEthernet3/2
description Uplink to WS-C3750
switchport access vlan 225
switchport trunk encapsulation isl
switchport trunk allowed vlan 225,700
switchport mode trunk
end
WS-C3750#sh run int Gi1/0/1
Building configuration...
Current configuration : 193 bytes
!
interface GigabitEthernet1/0/1
description Uplink to Catalyst4000
switchport trunk encapsulation isl
switchport trunk allowed vlan 225,700
switchport mode trunk
switchport nonegotiate
end
Thanks
