Using the show c7300 pxf accounting or show pxf Command
The following is an example of the
show c7300 pxf accounting
or
show pxf accounting
command with
sample output (not all Cisco IOS releases have both commands, but both commands produce the same
output):
Router>
show c7300 pxf accounting
PXF Utilization: 0 %
PXF Packet Counters:
Ingress from GE : 18 Egress to GE : 34
Ingress from LCs: 329 Egress to LCs: 8
Ingress from RP : 42 Egress to RP : 347
Using Debugging Commands and PXF
To enable all normal Cisco IOS packet debugging facilities, disable PXF. In configuration mode, use the
no ip pxf
command. Then use the Cisco IOS debugging commands to troubleshoot the problem.
To disable routing problems and control problems, you should not disable PXF. Only data packets pass
through PXF, and by debugging problems in Cisco IOS, you are changing packet treatment.
Ethernet Pause Frames on the NSE Gigabit Ethernet Ports
NSE-150 Gigabit Ethernet ports can always receive Ethernet pause frames because any version of Cisco
IOS that can be used to run the Cisco 7304 using an NSE-150 supports this functionality.
NSE-100 Gigabit Ethernet ports can receive Ethernet pause frames starting in Cisco IOS
Release 12.2(31)SB2.
For the NSE Gigabit Ethernet ports, Ethernet pause frames are automatically received if sent by a
neighbor device. The NSE Gigabit Ethernet ports only have the ability to receive Ethernet pause frames;
they cannot send Ethernet pause frames. No user CLI is necessary to configure Ethernet pause frames
for the NSE Gigabit Ethernet ports.
Ethernet pause frame counters can be viewed by entering the
show controllers gigabitethernet
command.
