Hello folks
Does anybody have any experience of poor performance (very low
throughput limitation) when using vlan-mapping in 12.2SX?
switchport vlan mapping enable
switchport vlan mapping 70 770
switchport vlan mapping 71 771
We've used it with no problems on a fairly well-loaded 6704/10gig port,
under 12.2(33)SXI. We had well over 30 vlans mapped.
What does "poor performance" mean?
Approximately 200kbit/s throughput.
Sounds somewhat like the translation is being punted to software/CPU
rather than done in hardware. I was seeing similar figures when I was
working the CPU hard to do a similar setup, until I figured out the
right way to configure it on the switch...
I'm using 12.2(33)SXI5 (soon to be SXI6) on an ME6524.
