Hello. I’m trying to model some of our production devices using a cEOS lab, and seem to have *just* about everything working correctly (mlag, vxlan, etc…) *but* I can’t seem to get routed .1q subinterfaces to operate correctly. The CLI configuration is accepted, and the interface status is “up”, but it shows an all-zeroes for the mac-address (which I read as a sign that something’s not right.) Results are consistent with docker-assigned MAC address and with Arista-OUI MACs taken from a prod switch (written to /mnt/flash/system_mac_address)
I vaguely recall .1q not being supported on earlier VEOS and CEOS versions, but on the 4.23.2.F CEOS image, VLAN operations seems fine, and the dot1q sub-interface configuration seemed to be accepted, so maybe I got my hopes up prematurely?
020540#sh run interf eth12
020540#sh interf eth12
020540#sh ip route connected | inc Ethernet12
Any assistance greatly appreciated!
I have the same issue running 4.23.2F. Only difference is the other end is in a vrf. Wondering if I missed something?
Hi Mencken and Wei,
The cEOS releases till 4.23.2F do not support sub-interfaces. More details are present in this discussion https://eos.arista.com/forum/dot1q-subinterface-support-on-ceos/
