Displays the TSPEC information sent from the clients that are enabled for voice diagnostics.
– show client voice-diag qos-map
Displays information about the QoS/DSCP mapping and packet statistics in each of the four
queues: VO, VI, BE, BK. The different DSCP values are also displayed.
– show client voice-diag avrg_rssi
Display the client’s RSSI values in the last 5 seconds when voice diagnostics is enabled.
– show client voice-diag roam-history
Displays information about the last three roaming calls. The output contains the timestamp,
access point associated with roaming, roaming reason, and if there is a roaming failure, reason
for roaming-failure.
– show client calls {active | rejected} {802.11a | 802.11bg | all}
This command lists the details of active TSPEC and SIP calls on the controller.
Step 9 Use the following commands to troubleshoot video debug messages and statistics:
– debug ap show stats {802.11b | 802.11a} ap-name multicast—Displays the access point’s
supported multicast rates.
– debug ap show stats {802.11b | 802.11a} ap-name load—Displays the access point’s QBSS
and other statistics.
– debug ap show stats {802.11b | 802.11a} ap-name tx-queue—Displays the access point’s
transmit queue traffic statistics.
– debug ap show stats {802.11b | 802.11a} ap-name client {all | video |
<client-mac>}—Displays the access point’s client metrics.
– debug ap show stats {802.11b | 802.11a} ap-name packet—Displays the access point’s packet
statistics.
– debug ap show stats {802.11b | 802.11a} ap-name video metrics—Displays the access point’s
video metrics.
– debug ap show stats video ap-name multicast mgid number —Displays an access point’s
Layer 2 MGID database number.
– debug ap show stats video ap-name admission—Displays an access point’s admission control
statistics.
– debug ap show stats video ap-name bandwidth—Displays an access point’s video bandwidth.
