Summit Family Switches
PD3-127401831 On a Summit X250e platform with 128 VRRP instances that are advertised for 100
milliseconds, the feature "don't preempt" is not working properly.
PD4-1102582531 In a PVLAN, network login MAC-based authentication does not work in ExtremeXOS
12.4.0.19.
PD4-427423116 When a dot1x client is authenticated at multiple VLANs, the output of the show
netlogin port command shows the client is sometimes authenticated at the local
server and other times at a RADIUS server.
Note: This occurs when dot1x and MAC authentication are enabled on the port.
PD4-1101069206 When configuring 2,000 VPWS instances, only 1,023 VPWS instances are created.
PD3-71725881 When configuring an optional name for the time zone/DST, the time zone name truncates
at seven characters. The system default is six characters.
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.
