[c-nsp] Resetting an err-disable state for non-Cisco XENPAK

[Ed Butler]

We're running some OpNext DWDM Xenpaks. We have noticed the following
behaviour on two different 6500-Sup720 chassis. 

1) Insert non-Cisco coded Xenpak
2) Xenpak is "rejected"
3) Use the "service unsupported transceiver" and "noerrdisable" commands
to allow Xenpak
4) Shutdown and re-enable the Xenpak
5) Xenpak is reported as "TenGigabitEthernet1/2 is down, line protocol
is down (faulty)"

I have tried reseating the Xenpak, but this does not clear the faulty
condition. The only way I managed to get the previous one up before was
to power cycle the 6704 card, which is hardly ideal.

Has anyone seen similar behaviour and resolved it without such drastic
measures?

Regards,
