ARP not showing in switch connected by trunk

Engineer-US
Level 1
Level 1

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
