Release Notes for ExtremeWare v6.2.1
VLAN QoS Between I/O BlackDiamond Modules
When using VLAN QoS on a tagged VLAN between i-series I/O modules and non i-series I/O modules
(G4X, G6X, F32T, and F32F), the “
show ports qosmonitor” will display the active ports between the
new and existing I/O modules as using different queues (7116).
MAC QoS
Broadcast MAC QoS does not take effect on non-”i” series I/O modules on a BlackDiamond. If an FDB
entry is created with a broadcast MAC address assigned to a QoS Profile, the entry will be ignored
against that QoS Profile on non-“i” series I/O modules (8841).
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 (1-579HD).
Bi-Directional Rate Shaping
1000BaseT Ports as Loopback Ports
If the loopback port for bi-directional rate shaping configurations is configured on 1000BaseT ports, the
speed of that port cannot be changed from 1000Mbps to 100Mbps as the bandwidth settings will not be
accurate when configured in 100Mbps mode.
ESRP
ESRP Instances Recognized by ESRP Aware Switches
ESRP Aware switches currently recognize only one instance of ESRP.
Multiple ESRP VLANs
If multiple ESRP VLANs share a host port, each VLAN must be in a different ESRP group.
ESRP Interoperability
We recommend that all switches participating directly in ESRP be running the same revision of
ExtremeWare. If it becomes necessary to mix ExtremeWare revisions, do not use any of the new ESRP
