    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!

    To view the system MAC on EXOS you would typically use the command show system and it will list the system MAC and system type at the top. If you are looking for a specific mac on a port or vlan you could use show fdb

    Issue not so trivial.

    For example there is ISP with a lot of Customers.
    ISP have no access credentials for Customers switches, but know that there is present switch with some S/N.
    How ISP can find MAC address of this switch?

    Thank you!

    Hi,

    When you say they know the S/N, How do they know that there is some S/N? Spreadsheet?

    Are all those switches (ISP and Customer side) from Extreme Networks?

    "When you say they know the S/N, How do they know that there is some S/N? Spreadsheet?" - they know because this switch is belongs to ISP.
    ISP and Customers has a lot of switches from different vendors (and Extreme too) in their networks.

    Is it possible to do with Asset Discovery Tool (ADT)?
    Or if ISP install NetSight in he's area?

    Thank you!

    ADT doesn't provide the MAC address, but I do see that Inventory Manager lists this information.

    Or, may be, we can do this through SNMP?

    Thank you!

    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)

    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.

    Also, may be, we can filter all MAC addresess in all networks by first 3 octets of MAC addresses?
    Like
    D88466 Extreme Networks 00E02B EXTREME NETWORKS

    000496 Extreme Networks

    000130 Extreme Networks

    To find in what exactly IP-networks is present Extreme switches.

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

    Thank you!

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