PD4-1142692318 On Summit X480 switches, L3 multicast traffic sent from a service VLAN/vMAN to VPLS
is not received at the VPLS peer.
Workaround: Two modes of operation are supported on ports that are configured as part of
a VPLS service VLAN.
Using the first mode, the following configuration is set for all VLANs on the port (VPLS
service VLANs and non-VPLS service VLANs):
1 IGMP snooping is configured as disabled. The default is enabled.
2 No IP address is configured.
Using the second mode, the following configuration is set:
1 Run the configure igmp snooping filters per-VLAN command. The default
is per-port.
2 If an IP address is configured for a VPLS service VLAN, run the configure
ipmcforwarding to-cpu off port <port> command. The default is auto.
PD4-448681226 The show l2stats command does not count ARP packets to the CPU, even though the
packet goes to the CPU.
PD4-489142320 One Gigabit ports set to auto on flap twice during a switch reboot.
PD4-489359602 Conflicting Link Fault Signal (LFS) alarms are shown when disabling local ports.
PD4-274249122 If a Summit switch populated with an XGM2-2bt module is rebooted, a false link up is
seen on 10G links connected to the XGM2-2bt ports approximately 30 to 50 seconds
before the switch has fully booted.
PD3-43606168 If sFlow does not have a collector configured using the configure sflow collector
command, the show log command generates the following messages:
08/23/2005 12:28:09.55 <Noti:sflow.debug.AddCntSmplFail> : Could
not add the counter sample for port 0:1020, as receiver is not
configured.
08/23/2005 12:07:49.55 <Noti:sflow.debug.AddCntSmplFail> :
Previous message repeated 61 additional times in the last 1200
second(s).
PD3-40266236,
PD3-40233121
Traffic on load share ports configured as redundant ports incorrectly moves to other ports
in the load share group during link transition.
PD3-202013281 Learning is disabled by default on remote mirroring VLANs. Running the enable
learning command on those VLANs may cause a loss of remote mirrored traffic.
PD3-202013298 The valid value range for tags on remote-mirroring VLANs is 1 to 4,094. Use these values
for configuring the remote tag in the enable mirroring command.
SummitStack
PD4-928567091 Running the synchronize command on a Summit X650 in a SummitStack causes the
system to time out and the stack to not synchronize for an extended period of time This
also results in the master node no longer being accessible.
PD4-787052219,
PD4-416129282
When a backup slot reboots and comes up, the switch experiences multiple stack link
flaps.
PD3-181304741 After inserting a XENPAK in a stack (XGM2-2xn, XGM-2xn) and performing an snmpwalk
on the entityMib entPhysicalDescr variable, XGM- is always shown, not the complete
module description.
