ExtremeWare 7.3.1b3 Release Notes 67
Workaround. Disable the Label Recording Request on the non-Extreme Networks MPLS switch and
reboot.
No Longer Display Stale TLS NHLFE Entries
Using an LSP tunnel label that is no longer valid creates stale TLS NHLFE entries that might cause lost
date packets. This can be caused by a configuration change, by an LSP going down and back up, or
when the label for a tunnel LSP is changed without the LSP going down and back up (PD2-203414601).
Workaround. Reboot the slot with the MPLS module.
MPLS Module Might Not Be Recognized
When you have more than one MPLS module in your chassis and you enable MPLS, one of the
modules might not be recognized. If an MPLS module is not recognized, reboot the slot
(PD2-199489301).
LSP NHLFE Not Updated
The values for the LSP NHLFE are not updated in the MPLS module when the downstream label is
changed. This might be the result of a change in the TLS’s address (PD2-203606001).
Workaround. Reboot the slot with the MPLS module.
Removing Second MPLS Module Causes Traffic to Stop
If you remove an MPLS module from a chassis with more than one MPLS module installed and using a
TLS tunnel, traffic stops. To work around this, replace the MPLS module (PD2-199171622).
Disabling One MSM Might Cause Loss of Throughput
If you disable one MSM in a dual-MSM configuration, you might lose half of the throughput on ARM
and MPLS modules (PD2-199171610).
The output of the
show diagnostics backplane utilities command shows slots with ARM or
MPLS modules as having only two backplane links, rather than the normal four backplane links.
Cannot Delete an LSP Previously Referenced by a TLS Tunnel
You cannot delete an LSP previously referenced by a TLS tunnel. To delete the LSP, first reboot the
switch (PD2-222522101).
EAPS Trap Not Sent if Connection is Through I/O Port
If the EAPS secondary port link is down, the EAPSStateChange trap is not sent to the management
station if the connection is through an I/O port that is part of the protected VLAN instead of to the
management port. To avoid this, connect the management station through the management port or an
I/O port that is not on the protected VLAN (PD2-180185834).
The card-down Option
In a fully redundant configuration, if you configure the card-down option in the configure
sys-health-check
command and checksum errors are detected, the MSM is not taken offline as
