surveillance via snmp
Various information about the node and the switch can be access via SNMP. Some of these can also be
set by snmp - but the setting is lost during a power reset. To persist a setting it must be set as part of

The CATV module can be setup, on/off mode:
switch -c 1
switch -c 0
# Turn CATV module off
switch -c 0
# Turn CATV module on

value can be made.
Below is an example of prioritization based on ToS value, where the switch engine will inspect the value
from 0 – 7. The switch holds 4 queues per port, where 3 is highest priority and 0 is lowest.
switch --set-port-ieee-tag-priority=0:1 #Enables prioritization for WAN port
switch --set-port-ieee-tag-priority=1:1 #Enables prioritization for LAN port1
switch --set-port-ieee-tag-priority=2:1 #Enables prioritization for LAN port2
switch --set-port-ieee-tag-priority=3:1 #Enables prioritization for LAN port3
switch --set-port-ieee-tag-priority=4:1 #Enables prioritization for LAN port4
switch --set-port-ieee-tag-priority=5:1 #Enables prioritization for CPU port
# applicable to 7/8 port models only
switch --set-port-ieee-tag-priority-ext=1:1 #Enables prioritization for LAN
port 5
switch --set-port-ieee-tag-priority-ext=2:1 #Enables prioritization for LAN
port 6
switch --set-port-ieee-tag-priority-ext=3:1 #Enables prioritization for LAN
port 7
switch --set-port-ieee-tag-priority-ext=4:1 #Enables prioritization for LAN
port 8
switch --set-ieee-queue-map=7:3 # ToS value of 7 will go to queue with highest
priority
switch --set-ieee-queue-map=6:3 # ToS value of 6 will go to queue with highest
priority
switch --set-ieee-queue-map=5:2 # ToS value of 5 will go to queue with next
highest priority
switch --set-ieee-queue-map=4:2 # ToS value of 4 will go to queue with next
highest priority
