ExtremeXOS 12.4.4 Release Notes
68
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.
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
PD4-1420046680 Powering up a SummitStack backup node causes a traffic drop of approximately 6
seconds when ports across slots are used for a LAG.
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.
PD3-126650411 A stackable system with two or more nodes may experience random VRRP master/
backup flapping issues after an MSM failover when configured with the maximum 128
VRRP instances using the minimum advertisement interval of 100ms and maximum
tracking entries.
PD3-209191768 After running the disable port all command on a SummitStack, some port LEDs
may sometimes light green even though ports are not up.
PD3-204744742 IPv6 neighbor-discovery in a management VLAN in a SummitStack resolves to the node
address of the stack master, instead of the stack MAC address.
