Gigabit Fiber Port Fails to Come Up when Connected to a Cisco Device

Issue

When connecting a Palo Alto Networks Firewall gigabit fiber interface to a Cisco router, switch, or other Cisco device the link does not come up.

 

Resolution

Check to see that the Cisco device does not have "speed nonegotiate" enabled. That setting is incompatible with the Palo Alto Networks gigabit fiber interface.
