ExtremeXOS 12.4.4 Release Notes

Mirroring
PD3-79867211 If you create a load sharing group (trunk), then enable mirroring to a port, the software
allows you to add the mirroring port to the load sharing group.
MPLS
PD4-464587012 All unicast traffic routed by MPLS is stopped when penultimate hop popping (PHP) is
enabled on all MPLS VLANs. VPLS traffic is not impacted.
PD4-476351932 Performing a restart process mpls or restart process ospf on a spoke
node in an HVPLS setup causes the Label Distribution Protocol (LDP) peer to go down
with the core node.
Workaround: Disable and enable MPLS.
PD4-475414370 The following warning message is seen numerous times after changing VLAN Virtual
Private LAN Services (VPLS) mappings:
<Warn:MPLS.LDP.InternalProb>
PD4-475414505 In more complex topologies, detour Label Switched Path (LSP) connections are not set
up.
PD4-475414558 Changing a Label Switch Router (LSR) ID causes all Label Distribution Protocol (LDP)
peers to go into a NonExistent state.
PD4-452308541 The secondary pseudo wire on an ESRP master switch does not take the secondary
core node pseudo wire after the primary core is rebooted.
PD3-157687121 ExtremeXOS software uses Control Channel Type 2 to indicate router alert label mode.
In MPLS Router Alert Label mode, VCCV packets are encapsulated in a label stack.
However, the existing VCCV packets are sent like a stack without any PW label.
PD3-184989177 When an LDP advertise static setting is set to all, all static routes are treated as
egress routes and egress LSPs are created. That is, a label is generated and advertised
for the static route. If the router at the end of the static route advertises a label matching
that static route, the LSP that was previously an egress LSP becomes a transit LSP. An
ingress LSP should also be created whenever a label is received, however, the ingress
LSP is never created.
Workaround: Do not use the LDP advertise static all configuration in situations
where an ingress LSP for a static route is required.
PD3-139423053 Running the show mpls rsvp-te lsp summary command on a system configured
with 2,000 ingress LSPs takes an excessive amount of time to process.
PD3-92653036 The show mpls label, show mpls rsvp-te label, and show mpls rsvp-te
lsp command output currently does not display egress LSPs using advertised implicit
NULL labels.
PD3-111544904 When a router receives an explicit NULL label, it is incorrectly treated as an implicit
NULL label, so rather than sending label 0, no label is sent.
PD3-93218551 If either an egress or a transit LSP traverses the system, and an MPLS labelled packet
containing a router alert label is received, that packet is not forwarded.
PD3-93069318 Only VLANs configured as protocol any should be added to MPLS.
PD3-104731701 When a traceroute is performed by setting the MPLS TTL to the IP TTL, ExtremeXOS
does not correctly send back an ICMP response. The result is “*” characters in the
traceroute for the routers that timed out. If a route is available, ExtremeXOS should
attempt to send back an ICMP response.
PD3-93630853 LDP should not advertise a label mapping for a direct VLAN that does not have IP
forwarding enabled.
