Clarifications, Known Behaviors, and Resolved Issues
Bi-Directional Rate Shaping
Locking and Unlocking Learning
If you configure a rate shaping port to lock learning and unlock learning, the loopback FDB is not
flushed. This causes traffic destined for the port to be flooded. You must manually flush the FDB using
the
clear fdb command (PD2-124568416).
Loopback Port Must be on Same Module
The loopback port must be on the same module as the rate shaped ports. Though you can configure a
loopback port on another module, this is still not a supported configuration (PD2-124299901).
1000Base-T Ports as Loopback Ports
If the loopback port for bi-directional rate shaping configurations is configured on 1000Base-T ports, the
speed of that port cannot be changed from 1000 Mbps to 100 Mbps as the bandwidth settings will not
be accurate when configured in 100 Mbps mode.
Changing the Configuration of a Loopback Port
If you change the configuration (speed, duplex setting, etc.) of a loopback port, you must either save the
configuration and reboot the switch, or delete the port from the VLAN and add it back
(PD2-127582534).
EAPS
WAN Modules Not Currently Supported with EAPS
Do not use WAN modules with EAPS (PD2-120015201).
Do Not Configure a Hello Time of 0
Though the minimum hello time is 1, the switch accepts a hello time of 0. Do not configure the hello
time to 0, as this effectively disables EAPS (PD2-119139425).
A Large EAPS Configuration with a Link Transition
If you configure a single EAPS ring with 64 domains and more than 3,000 VLANs, a link transition
could cause a 300 second traffic outage. To work around this, delete the old FDB entries using the
clear
fdb
command (PD2-119139401).
Changing the Protected VLAN Tag
Do not change the protected VLAN tag if EAPS is configured and enabled. Doing so can create a loop
in the network. First disable EAPS, then make changes (PD2-121610287).
