Number Description
Q01911582 After you restart the stack, few dynamic ports may not move to Red and
VoIP VLANs.
Q01904189 When you authenticate IP Phones with non-EAP or ADAC, and then restart
the base unit or the last unit, not all ports may be authenticated after the
restarted unit rejoins the stack.
Workaround: Disable and then enable ADAC on the respective ports.
Q01900513 OSPF hello packets may not be captured on 5530 ports when you use ADST
Mac address based mirroring mode.
Q01897761 When you use Device Manager with IGMP, it may display some incorrect
information in the ActiveQuerier and QuerierPort fields under VLAN,
VLANs, Snoop menu. This is a known issue.
Q01895450 When you authenticate IP Phones using non-EAP and ADAC becomes
operationally disabled, it may take up to 300 seconds (5 mins) until EAP
clears the multihost non-eap-mac table. If this is not desirable, EAP can
be bounced on the respective ports.
Q01895070 After you restart a switch or stack with Fail Open enabled (NSNAS connected
in the network), some devices may show as a green IP in the red VLAN. If you
run the
shutdown/ no shutdown
command, the ports on stack will resolve
the issue for both PCs and passive devices. Or, you can enter the
ipconfig
/release; ipconfig /renew
command on the PC command line.
Q01893356 After you restart the stack, some NSNA MAC authenticated devices (in the
green VLAN or green filter) may remain with a red IP although the VLAN is
green. Run the
shutdown/ no shutdown
command to resolve the issue.
Q01865091 NSNA static MAC authenticated clients may not be re-authenticated on Base
unit after it is restarted.
Q01440362 If you use DHCP relay on multiple hops, Nortel recommends that you
configure the DHCP forward path on all hops to the DHCP server.
Q01909890 If you use a policy to filter a multicast flow with a system classifier with
known-mcast or unknown-mcast options configured, it will only match non-IP
traffic for the Ethernet Routing Switch 5600 Series.
Q01921407 In certain topologies, when you connect multiple PIM routers to the same L2
device, both the DR and non-DR routers may install the same OIF, resulting
in duplicate packets for receivers across the L2 device.
Workaround: Connect only a single PIM router to the L2 device.
Q01929584-01 When you use Web-based management with an IPv6 address, the response
time may be noticeably slower than when you use Web-based management
with an IPv4 address.
Q01839477 If you unplug an IP phone that is on a call or receives line tone, all of the
other phones on the VoIP VLAN receive UDP packets (30-35 packets/sec)
with the Source Address=BCM and Destination Address=IP-phone of the
removed IP phone. The packet flood lasts 20-25 seconds.
