Displaying AVB Information

The completae set of "show" commands are detailed in the ExtremeXOS 16.2 Command Reference Guide. Some of the more commonly used commands are outlined here.

gPTP

Detailed information about gPTP can be displayed using the following set of commands:

show network-clock gptp ...

For example, the show network-clock gptp ports command can be used to view the gPTP properties of a given port, and is useful for debugging when the summary avb command shows that the port is not operational for gPTP.

# show network-clock gptp ports 1   
Physical port number               : 1   
gPTP port status                   : Enabled   
Clock Identity                     : 00:04:96:ff:fe:51:ba:ea

MSRP

Detailed information about MSRP can be displayed using the following set of commands:

show msrp ...

Several that are commonly used are:

show msrp
show msrp streams
show msrp listeners
show msrp streams propagation

Examples of these commands are shown below.

The show msrp command displays the summary information included in the show avb command, but also displays the total number of streams and reservations on the switch.

# show msrp 
MSRP Status                   : Enabled   
MSRP Max Latency Frame Size   : 1522   
MSRP Max Fan-in Ports         : No limit   
MSRP Enabled Ports            : *1ab    *2ab    *10ab   *11ab    12
                                 13      14      15      16      17
                                 18      19      20      21        
Total MSRP streams            : 2   
Total MSRP reservations       : 6       
Flags:  (*) Active,              (!) Administratively disabled,           
        (a) SR Class A allowed,  (b) SR Class B allowed

The show msrp streams command displays all of the streams that the switch is aware of.

# show msrp streams    
Stream Id              Destination     Port  Dec    Vid  Cls/Rn     BW

   Ready : Listener Ready  

The show msrp listeners command displays all of the listeners the switch is aware of. If the declaration type is either Ready or RdyFail, a reservation has been made, and the Stream Age will show the length of time this reservation has been active.

# show msrp listeners

The show msrp streams propagation command is useful for debugging the propagation of Talkers and Listners for each stream.

MVRP

Other than the MVRP summary information displayed in the show avb command, information about dynamically created VLANs is shown using the "vlan" commands as follows.

In the show vlan command, it can be seen that SYS_VLAN_0002 is a dynamically created VLAN due to the “d” flag.
