Switching

Hi,

I have a list of computer MAC addresses in my network. I need to locate the switch and port of all the listed MAC address. We have around 18 Ex switches and 60 odd computers to locate. The VLAN assigned to the computer are L3 VLAN.

There should be a way to do this but I cant find it. Any leads would be helpful.

Hi Harish,

Even if the vlan is configured as a IRB vlan, the mac addresses of the PC's connected to the switch port will be displayed under "show ethernet-switching table"

root# run show ethernet-switching table

MAC flags (S - static MAC, D - dynamic MAC, L - locally learned, P - Persistent static, C - Control MAC
SE - statistics enabled, NM - non configured MAC, R - remote PE MAC, O - ovsdb MAC)

Ethernet switching table : 3 entries, 3 learned
Routing instance : default-switch
Vlan MAC MAC Age Logical NH RTR
name address flags interface Index ID
default 84:c1:c1:ac:07:c5 D - ge-0/0/2.0 0 0
test_112 84:c1:c1:ac:07:c4 D - ge-0/0/1.0 0 0
vlan_test 30:7c:5e:47:b3:15 D - sxe-0/0/0.0 0 0

root# run show vlans test_112

Routing instance VLAN name Tag Interfaces

root# show vlans test_112
vlan-id 112;
l3-interface irb.112;

root# show interfaces irb.112
family inet {
address 112.112.112.112/24;
}

{master:0}[edit]
root# show interfaces ge-0/0/1.0
family ethernet-switching {
vlan {

Thanks that worked for me 🙂

Try this one:

show ethernet-switching table
