[j-nsp] Weird Port Problem

[Paul Stewart]

Hi there..

 

We have a customer we migrated off a Cisco 7600 over to an MX480.

 

Long story short we're having performance issues and have isolated it down
to some questions ;)

 

This is a 20GE+2X10GE linecard - customer port is using a copper 10/100/1000
SFP.  Port is hard coded to 100/full on both sides.

Opened ticket with JTAC and so far not getting anywhere despite requesting
an escalation - they have been "analyzing" this for over 24 hours now with
no idea.

 

According to some docs, FIFO errors mean "replace the PIC immediately" which
I find hard to believe - this could be a classic cat5 issue or an SFP issue
but before knocking the customer down would rather get some feedback
please..

 

Customer side is a watchguard firewall unfortunately

 

Thanks,
