QoS Commands
enable isq vlan
enable isq vlan <vlan name>
Description
Enables Intra-Subnet QoS (ISQ) on a per-VLAN basis.
Syntax Description
Default
Disabled.
Usage Guidelines
This command is not available in ExtremeWare v6.0 or later.
ISQ allows the application of QoS commands to be effective within a subnet (VLAN) instead of only
applying the QoS when traversing a routed subnet. The command syntax for all IPQoS commands
remains the same; ISQ is simply enabled on a per VLAN basis.
Because ISQ instructs the switch to look at IP addresses within a VLAN, the normal MAC-based
learning and refreshing for layer 2 switching is altered for traffic that matches an IPQoS traffic
grouping. Instead, learning and refreshing is done based on IP information in the packets. As a result, it
is necessary to increase the FDB aging timer above a normal ARP table refresh time to 50 minutes (3,000
seconds). This occurs automatically when ISQ is enabled. ISQ should not be used on VLANs with
clients that have statically defined ARP tables.
Example
The following command enables ISQ on a VLAN named accounting:
enable isq vlan accounting
