JunosE 10.3.2 Release Notes

Known Problems and Limitations
„ You cannot use the highest sensitivity bit-error rate setting (a value of 9)
associated with APS/MSP alarm when you issue the
threshold sd-ber
command to configure a cOCx/STMx line module with cOC12-APS-capable
IOAs. [Defect ID 72861]
Work-around: Use only a value in the range 5–8 when you issue the threshold
sd-ber command for this module combination, as in the following example:
host1(config)# controller sonet 2/1
host1(config-controll)# aps group boston
host1(config-controll)# aps protect
host1(config-controller)# threshold sd-ber 6
SRC Software and SDX Software
„ The SRC client does not prevent you from changing the name of the router
while the client is connected to the SAE, resulting in SAE issues such as lost IP
addresses and stale users. [Defect ID 77102]
Work-around: To change the router name while the SRC client is connected to
the SAE, shut down the SRC client, change the name, then re-enable the SRC
client.
„ When multiple IPv6 interfaces are configured with policies attached from SRC,
only some of the IPv6 interfaces have the policies attached. [Defect ID 179498]
„ Changing the SSCC status (enable/disable) while IPv6 interfaces are configured
might cause the SRP to reset. [Defect ID 179537]
Stateful SRP Switchover (High Availability) and IP Tunnels
„ When you issue show commands as soon as the CLI is available after a stateful
SRP switchover, the commands can hang until the warm restart is completed.
[Defect ID 85306]
„ A packet loss sometimes occurs during stateful SRP switchover when you use
the
ping command on a router that is configured for OSPF graceful restart, and
is connected to a helper router in the OSPF IPv6 broadcast network and
another helper router in the OSPF IPv6 backbone area. [Defect ID 181470]
„ ERX7xx model, ERX14xx model, or ERX310 router:
‰ When you use the ping command with the IPv6 address of the helper
router in the multicast area as the destination address and the
loopback address of the helper router in the backbone area as the
source address, a packet loss of 2 seconds occurs for the first stateful
SRP switchover. However, no packet loss occurs for successive stateful
SRP switchovers.
‰ When you use the ping command with the IPv6 address of the helper
router in the broadcast network as the destination address and no
source address when stateful SRP switchover is performed the first
time, an identical packet loss occurs. In this case too, no packet loss
occurs during subsequent switchovers.
