Quick question on Brocade VLAN interfaces
I'm running Brocade CER routers in my network at the moment. VLAN interfaces on Brocade are implemented as ve interfaces. Brocade for some reason decided not to implement interface counters for ve interfaces on the CES/CERs, so of course I don't get any utilization graphs for these interfaces.
Is anyone out there running MLX or XMR? Out of morbid curiosity, do the VLAN interface octet/packet counters work on them?
Thanks

The MLXs only support per-VLAN counters on the gen 2 or higher line cards. Pretty sure that's only the 8x10G and 2x100G cards, it may include the 24x10G but I haven't really tested.

It is the same on MLX and XMR. Counters don't work with ve interfaces.

This is common across a great many vendors and platforms.
You sometimes have luck upgrading the software, or hoping for a future implementation, but often it's a limitation of the ASICs involved, or just that the vendor doesn't see any utility in implementing the counters.
I remember being super pleased when Cisco implemented these counters for sub-interfaces, way back when. :)

It's a hardware limitation in the older cards. The newer cards support it but they don't expose the counters in a logical manner (ie. the IF-MIB tables still return 0). The CER-RT is loosely based off the gen 1.1 cards so it won't get support, the new 4x10G CER is the same.
The counters are available in brcdVlanExtStatsTable on supported hardware.
I guess it is funny to me how all these vendors posture themselves as being cloud-friendly and virtualization-ready and what not, yet it doesn't occur to them that their product might be used to segment a network into VLANs and that people might actually want to see the utilization on those VLANs.
Such is life, I guess. lol
