Hello!

Some strange question/task )))

There is big nework.
We have serial number of switch X670.
How can we find MAC address of this switch?

Thank you!

Also, may be, we can filter all MAC addresess in all networks by first 3 octets of MAC addresses?

Do you have all variants of theese 3 octets of MAC?

Thank you!

EXOS stacks use 020496, so you may see that show up.

A NMS is your easiest route. But if you don't have one of those just laying around you could use the Asset Discovery Tool to find the SN# and IP. Then you can just login of use SNMP. A SNMP get for ".1.3.6.1.2.1.2.2.1.6.1001" should do it.

You can get the MAC with the following OID
Name: ifPhysAddress
Type: OBJECT-TYPE
OID: 1.3.6.1.2.1.2.2.1.6
Full path: iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).interfaces(2).ifTable(2).ifEntry(1).ifPhysAddress(6)
