The MPX 10G Port connected to LRM 10Gig XFP switch port did not come UP and is always marked DOWN.
A customer experienced that when they connect their MPX 10 Gig port to a Cisco Switch LRM 10 Gig XFP, the port fails to come up, even after trying different interface settings.
The NetScaler MPX 10 Gig ports works only with SR XFPs (Short Range XFPs).
MPX NetScaler connecting to LR XFPs on the switch side might work but is not supported.
The quote from the Installation and Configuration Guide:
“The XFPs shipped with the system are10BASE-SR (Short Range), multi-
purpose optical transceiver modules for data transmission applications at 850nm.”
Refer to Installation and Configuration Guide for further details.
XFP = 10Gig small form factor optical transceiver
LRM = Long Range Multimode
