How to view the port of a terminal device access switch

The topology is the terminal device -- access switch -- aggregation switch -- core switch

For example, check the access port of the 192.168.3.1 device.

1. Core

Confirm the MAC address and interface of the Terminal

<Devce A> dis ARP | include 192.168.3

Type: S-static D-dynamic M-multiport

IP address MAC address vlan id interface aging type

192.168.3.1 0018-7d2c-5dab 30 bagg1 19 d

192.168.3.18 0018-7d2c-5cb7 30 bagg3 20 d

2 \ confirm that 3.1 belongs to bagg1 and check which aggregation switch is bagg1

<Devce A> dis ARP | include bagg1

Type: S-static D-dynamic M-multiport

192.168.200.102 0cda-419e-5974 200 bagg1 18 d

3. Check which port of the aggregation switch 192.168.200.102 is used for the 3.1 Access Switch.
