ExtremeXOS 12.3.4 Release Notes
82
PD3-111344472 ScreenPlay allows you to configure DHCP but you cannot enable DHCP.
Security
PD3-205012219 A source-ip-lockdown dynamic deny acl counter is not working properly and increments
valid traffic from a trusted client.
PD3-186939931 Ingress mirroring is not working for DHCP snooping when snooping is enabled on
BlackDiamond 12800 series switches. DHCP snooping works correctly when DHCP
snooping is disabled.
PD3-75120608 The unconfigure radius and unconfigure tacacs commands do not reset the
timeout value to the system default of 3 seconds.
sFlow
PD3-205380274 sFlow is not working on ports that are included in BVLANs, SVLANs, and occasionally
vMANs. sFlow can be enabled and configured for ports in BVLANs, SVLANs, and
vMANs, but nothing is sent to the sFlow collector.
SNMP
PD4-705730556 AES/3des users created using ExtremeXOS 12.3.1 software cannot be used for SNMP
operations in ExtremeXOS 12.1 or earlier releases. This may cause the SNMP master to
crash.
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.
PD3-39411271 icmpInMsgs counter will display the incoming ICMP packets for VR-Default only.
Spanning Tree Protocol
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.
PD3-189927343 A temporary loop occurs when a root bridge is taken down by disabling all ports or
powering down the switch.
Stacking
PD3-136493921 If a switch is added to a stack whose master switch has a license level that is greater
than the level of the switch, the switch will fail. The complete condition can be seen using
the show slot detail command. In this state, the switch does not have AAA services
available. You will only be able to log into the switch using the failsafe account that was
last assigned to it. You must log into the switch to upgrade the license. If the switch is not
using the failsafe account configured on the stack, you can use the synchronize
stacking {node-address <node-address> | slot <slot-number>} command to
copy the failsafe account information from the master switch to the failed switch NVRAM.
You can also use the configure stacking license-level command to configure
a license level restriction on the entire stack and then reboot the stack. Once the stack is
restarted, there is no longer a license mismatch, enabling you to log into the switch and
upgrade the license. From the master switch, run the unconfigure stacking
license-level command to get the stack to operate at the desired license and then
reboot the stack.
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.
WAN PHY
PD3-101226461 When show wan-phy commands are run on non WAN PHY ports, the ports display the
headers. It should only display the error wan command is not supported on
non-wanphy port 25.
