Open Issues, Known Behaviors, and Resolved Issues

ExtremeXOS 12.4.2 Release Notes

PD4-1329832557 Exp examination and replacement configuration is getting retained after a user deletes

MPLS from current VR and adds it to another VR.

Workaround: Use “unconfigure MPLS” command before deleting MPLS from the VR that

is currently running MPLS, then add MPLS to a different VR.

PD4-822663105 Uploading or downloading a configuration results in an MPLS configuration being lost as

MPLS is not deleted from the VR-Default.

PD3-208178928 Adding a static route with an MPLS LSP may cause one of the following problems:

• If a static route is added with an MPLS LSP whose transport setting is “IP traffic

deny,” the route is displayed with an invalid nexthop in the show iproute mpls

command output.

• When a static route is added with an MPLS LSP that is not present in show

iproute mpls command output. For example, if there are 17 RSVP-TE LSPs to the

same destination, only 16 LSPs are eligible for carrying traffic because of a maximum

ECMP path limit of 16. Adding static routes with 17 LSPs results in the same

observation.

Multicast

PD3-2841008 With PIM, when small-sized multicast streams are ingressed at line rate, there is an

initial packet drop of 50% to 70%. This is seen on BlackDiamond 8800 and Summit

X450 switches.

PD4-901778542 The command mrinfo <neighbor ipaddress> from <source ipaddress> is

not displaying the entire interface when the source IP address is changed.

Spanning Tree Protocol

PD4-1161434651 MSTP edge ports are not correctly learning MAC addresses.

Workaround: To clear the wrong MAC address learned on the edge port, run the clear

fdb command. You may also wait until the FDB is automatically refreshed (default

refresh value is 300 seconds).

PD4-1238838391 Process stp signal 11 code: Program terminated with signal 11, Segmentation fault.

PD4-492384091 When scaled to the maximum number of Rapid Spanning Tree Protocol (RSTP) domains

with EMISTP port mode, an IGMP packet loops for a short period of time when a link

flap occurs.
