Leave All Timer
Leave All Timer sets the duration of the Leave All Period timer for GVRP in
milliseconds. Each port has a single Leave All Period timer. Leave All Timer must
be larger than Leave Timer; the default is 1000 milliseconds.
Port Isolation
Turn on port isolation to block communications between subscriber ports. When
you enable port isolation you do not need to configure the VLAN to isolate
subscribers.
Switch Mode
Select
Standalone
to use both of the AAM’s Ethernet ports (
LAN 1
and
LAN 2
) as
uplink ports.
Note:
Standalone mode is recommended for network topologies
that use loops.
Use
Daisychain
mode to cascade (daisychain) multiple AAMs. The AAM uses
Ethernet port one (
LAN 1
) as an uplink port to connect to the Ethernet backbone
and uses Ethernet port two (
LAN 2
) to connect to another (daisychained or
subtending) AAM.
Note:
Daisychain mode is recommended for network topologies
that do not use loops.
Priority Queue Assignment
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service. Frames without an explicit priority tag are given the default
priority of the ingress port. Use the next two fields to configure the priority level-to-physical queue
mapping.
The switch has 4 physical queues that you can map to the 8 priority levels. On the switch, traffic
assigned to higher index queues gets through faster while traffic in lower index queues is dropped if the
network is congested.

Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d
standard (which incorporates IEEE 802.1p).
Level 7
Typically used for network control traffic such as router configuration messages.
Level 6
Typically used for voice traffic that is especially sensitive to jitter (jitter is the
variations in delay).
Level 5
Typically used for video that consumes high bandwidth and is sensitive to jitter.
Level 4
Typically used for controlled load, latency-sensitive traffic such as SNA (Systems
Network Architecture) transactions.
Level 3
Typically used for “excellent effort” or better than best effort and would include
important business traffic that can tolerate some delay.
Level 2
This is for “spare bandwidth”.
Level 1
This is typically used for non-critical “background” traffic such as bulk transfers that
are allowed but that should not affect other applications and users.
Level 0
Typically used for best-effort traffic.

Apply
to save your changes to the AAM’s volatile memory. The AAM loses
these changes if it is turned off or loses power, so use the
Config Save
link on the
navigation panel to save your changes to the non-volatile memory when you are
done configuring.
