ExtremeWare 7.0 Release Notes 45

Access List Precedence Intervals

Access lists with large intervals (greater than 10) between precedence values now perform better.

Previously, configuring access lists using large intervals (greater than 10) between precedence values

could result in several-minute delays for each

add transaction. We still recommend that you configure

ACL precedence with an interval value of less than 5 between each rule. This configuration avoids any

adverse performance issues such as very long delays between

add transactions and loss of access to

configuration sessions (1-B6F48, 15717, 15718).

Creating Access Lists from Multiple Sessions

When creating or modifying access control lists, please ensure that no other administrator sessions are

attempting to create or modify the system access control lists simultaneously. This may result in data

corruption (1-579HD).

QoS and dot1p

If you configure VLAN QoS to a higher precedence than dot1p QoS using QoStype priority, egress

traffic will go out through Q0 (1-CH3MD).

5,120 Access Lists and SNMP

Although you can configure up to 5,120 ACLs, SNMP only recognizes 1,280. Deleting an ACL that is not

recognized by SNMP generates the following error (PD2-64880917):

<WARN:SNMP> SNMP IPQOS Could not find entry instance 5083 to delete

Monitoring QoS and the show port qos Command

When monitoring QoS, do not use the show port qos and enable qosmonitor commands on the

same port at the same time. These commands in conjunction lock the console session. However, the

syslog does capture the output (PD2-64202681, PD2-80836531).

Ingress QoS

Ingress QoS Not Supported on Other Modules

Ingress QoS is only supported on “

” series modules. Though you can configure ingress QoS on other

modules, the feature is not supported and the configuration has no effect (PD2-129625008).

The show ports ingress stats Command Truncates

The Tx Xoff column in the show ports ingress stats command output truncates values to seven

characters (PD2-130148001).
