Number Description
Q01346792 If you are unable to get the switch to transmit LLDP network policy type,
length, and value (TLV), ensure that the following two conditions are true:
• ADAC is enabled on the port
• “Filter Unregistered Frames” option is set to “Disabled” on the
ADAC-enabled port
Refer to Nortel Ethernet Routing Switch 5500 Series Overview – System
Configuration (NN47200-500) for more information.
Q01353603 When attempting to download the license file using the JDM after a previous
attempt, the switch may return a “commitFailed” error. You may also receive
this error if you enter an invalid license file name.
Q01366965 The CLI behavior related to PoE TLVs (MED "Extended Power-Via-MDI"
and DOT3 "Extended Power-Via-MDI") is inconsistent when enabling them
for transmission on non-PoE switches (no error message is generated in
either instance).
Q01370360 When using the CLI, you may see an inconsistency in output for the
show spanning-tree <mstp|rstp> port <config|status>
<port>
commands in MSTP or RSTP mode. This only occurs when there is
no link on the port for which you are viewing statistics.
Q01371237 The 5500 Series switch supports 32 MLT groups. These can be configured
using the CLI, JDM, and the Web interface. Note that the CI allows you to
configure only six of the 32 MLT groups.
Q01379149 You must ensure you set the same speed on link partners. That is, if the
speed for a port is set to 10 Mbps, any device connected to that port (for
example, an IP phone), must also be running at 10 Mbps.
Q01380260 You may experience an inconsistency between the base unit (BU) and
non-base unit (NBU) ports when using the EAPoL authentication process
with UBPs. Specifically, on the NBU, if a policy cannot be installed, the switch
will send a success and then immediately send a failure.
Q01384613 There is a scaling limitation for TLV in the 802.1ab feature. If you have an
8-unit stack that is fully connected and has 256 VLANs configured, you might
experience that the DOT1 VLAN name TLV is not sent properly.
Q01385870 You can configure port mirroring using NNCLI, CI and Web-based
management only.
Q01391522 When using the CI to create STP groups, you may receive "The Group has
no VLAN members" error message, which then interferes with subsequent
configuration. Toggle the STP group field to continue configuration.
Q01394363 There is a discrepancy between the CI and the JDM when viewing port
statistics displayed for received packets.
