Clarifications and Known Behaviors
ExtremeWare 7.3.1b3 Release Notes 83
Access List FDB Entries not Cleaned Up
If you delete an access list with the “f” flag (flow rule), the associated FDB entries might not be cleared
(PD2-110082518).
Access Lists Using the IP Deny Any Rule
When using an access control list with an IP deny any rule, all ICMP traffic will be blocked within a
VLAN (Layer 2). If using an access list with an IP deny any rule across VLANs (Layer 3), ICMP traffic
will not be blocked.
Access Lists and IP Fragmentation
When using IP fragmentation, since the TCP header is treated as data and only the IP header
information is being replicated in each packet, access-lists that apply to that flow will not apply as the
TCP/USP port information is not included after the first fragment (for subsequent fragments).
QoS Configuration Bandwidth Parameters
Minimum and maximum percentage parameters for a specific port on the default VLAN will not be
saved across reboots. The configuration change will be applied when configured. This issue only occurs
on the BlackDiamond (15500).
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 might result in data
corruption (1-579HD).
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).
MPLS
Cannot Delete TLS VLAN After Deleting TLS Tunnel When MPLS is Disabled
You cannot delete a TLS VLAN after you delete a TLS tunnel when MPLS is disabled. To delete the TLS
VLAN, enable MPLS or reboot the system (PD3-2553271).
IP Interface of Local End-point VLAN for TLS Tunnel or VPLS Can be Modified
When you configure a VLAN with loopback-mode and IP forwarding enabled, and an IP address, a TLS
tunnel or VPLS is configured using this VLAN as the local end-point. You can disable IP forwarding
