ExtremeXOS 12.5.4 Release Notes
78
PD4-1867670001 VM-tracking synchronization status is complete before all policy files are downloaded to a
switch.
PD4-1857577536 A switch shows the SSH status as "Module not loaded" when upgrading the switch from
ExtremeXOS 12.1.5.1 to v1252b0-br-ssh-license-1 with Extreme Networks SSH software
module (ssh.xmod) license file.
Workaround: After upgrading to ExtremeXOS 12.5 software, uninstall and reinstall the
SSH software module (ssh.xmod) and enable the SSH license.
PD4-1583984848 On Summit X480 switches, IPv6 slowpath traffic is not forwarded across tunnels.
PD4-1656226261 A system crash occurs when regression testing SNTP and DNS.
PD4-1679504312 A Summit X460 switch crashes when MSTP is configured with 64 MSTIs and 1,000
VLANs.
PD4-1738392317 When downloading an image using the rescue procedure, the new download has a
different name than the regular download.
PD4-1805624847 Process HAL is terminated with signal 11 when 4,000 VLANs are configured and a
system reboots.
PD4-1436226210 With default ethertype (0x88a8) configured, Summit X460 and X480 switches do not
display an error message when adding a port as tagged to a vMAN when the port is
already part of a tagged VLAN. When the port is already part of an EAPS control VLAN,
EAPS goes to a failed state.
PD4-1592270392 A Summit X480 stack may get stuck in the backup state after running the show switch
command after a system reboot or failover.
PD4-1679652990 VPLS is not sending untagged vMAN traffic type 88A8 through Summit X460 switches.
PD4-1676631313 When disabling sharing on a load-shared port that is part of multiple VLANs, VLAN
statistics shows a “-” for some VLANs.
Workaround: Unconfigure and reconfigure VLAN statistics.
PD4-1659644826 VLAN statistics monitoring is unconfigured for a specific VLAN if the VLAN name is
changed.
PD4-1648023331 A Summit family switch configured with MLAG does not reply to the first ARP request
received on an ISC port.
PD4-1664831900 VLAN statistics are included in the output of the show configuration command for
load-sharing member ports even after the unconfigure ports monitor vlan
command is issued.
Workaround: Disable sharing, remove the VLAN statistics configuration, and enable
sharing.
PD4-1673106807 For certain match conditions involving SIPv6 and DIPv6, packets may not hit an ACL in a
Summit X450a switch.
PD4-1637091230 With 4,000 VPWS sessions, traffic recovery takes approximately 8 minutes before a port
flap occurs.
Workaround: On a Summit X460, it is recommended that you only configure 1,000 VPWS
instances.
PD4-1589959110 When adding ECMP routes using OSPF, a route flap occurs.
PD4-1603951551 On a Summit X460 stack, the following kernel warning is seen in the log during a
failover.
<Warn:Kern.Card.Warning> Slot-1: select_mux:line 250:I2C I/O
operation failed
PD4-1591238321 VM tracking repository synchronization is not working properly when using a remote FTP
server.
PD4-1590249340 Clearing FDB entries when a Summit X480 switch learns 512,000 MAC addresses from
MLAG ports disrupts MLAG peer TCP sessions.
