Nimbostratusmac addresses
alright,
i'm a bit confused by the mac address being created per interface based on the vlan.
let me give the example: F5 LTM 8900, running 10.2.4 Build 817.0 Hotfix HF7
up stream switch,...

NoctilucentYou're correct on the zero placements. This article may provide some clarity relating to determining what MAC addresses you may see at the switch level, as layer 2 and 3 traffic will likely have different MAC addresses:

brucecmc_163171thanks cory...yes, I've read that doc...which is what prompted my questions...clear as mud to me...lol...going to read through it again...maybe the light will come on...- brucecmc_163171another odd thing, when I run the show sys mac-address | grep -I interface, it doesn't display the mac of the interface I was referencing above that isn't showing up anywhere (0:1:d7:d1:5e:3). BUT, if I grep just for the mac, it returns 0:1:d7:d1:5e:3 net vlan xxxxx_330 mac-true xxxx being my random naming convention
- Cory_50405So the vlan interface will be the source of IP traffic, whereas the physical interface will source things like STP. Sounds like the 03 MAC you're referring to is assigned to your 330 vlan, which should be visible in the GUI.
- brucecmc_163171sorry for delay in response...chasing other squirrels...and yes, the 03 mac is associated with vlan 330...I just don't see the mac out right in the cli (show sys mac-address). it is in the gui, and if I grep the mac, I do in fact get a return.
- Cory_50405Does it show up in ifconfig from bash shell? ifconfig -a
- brucecmc_163171it does...
- brucecmc_163171which does help me as it relates to determining what mac i'm seeing on the switch...just wasn't clear on how the mac's were getting created and which ones were which...
