To display the control packet exchange history between the Network Interface Manager software process (NIF Mgr) and the StackWise
Virtual Link (SVL) interfaces, use the show platform software nif-mgr switch command in privileged EXEC mode.
show platform software nif-mgr switch {switch-number | | active | | standby} R0counters {slot | slot-number | } {port | | port-number | }packets {slot | slot-number | } {port | | port-number | } {switch-info}
Syntax Description
switch {switch-number | active | standby}
|
Displays information about the switch. You have the following options:
-
switch-number.
-

|
slot slot-number
|
Specifies the supervisor module slot number on the device.
|
port port-number
|
Specifies the port number on the module.
|

Usage Guidelines
The output of the show platform software nif-mgr switch active R0 counters command displays counters for LMP and SDP packets that are transmitted.
The output of the show platform software nif-mgr switch active R0 switch-info command displays the SVL links details and the protocol flap count on each of the links.
-
LMP to FED
-
SDP to FED
-
FED to LMP
-
FED to SDP
-
Stack Manager to SDP
-
SDP to Stack Manager
The output of the show platform software nif-mgr switch active R0 packets command displays the timestamp details of the LMP and SDP packets transmitted.
-
Timestamp of last 10 LMP frames from FED
-
Timestamp of last 10 LMP frames to FED
-
Timestamp of last 10 SDP frames from Stack manager
-
Timestamp of last 10 SDP frames to Stack manager
By default, the packet cache count per SVL port during bootup is 10. To set the packet cache count per port, use the set platform software nif-mgr switch command.
