Known Problems and Limitations

SONET
z
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
z
When multiple IPv6 interfaces are configured with policies attached from SRC, only
some of the IPv6 interfaces have the policies attached. [Defect ID 179498]
z
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
z
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.
−
E120 router or E320 router
>
When you use the
ping
command with the IPv6 address of the helper router
in the broadcast network as the destination address and the loopback
address of the helper router in the backbone area as the source address, no
packet loss occurs.
>
When you use the
ping
command with the IPv6 address of the helper router
in the multicast area as the destination address and no source address, a
packet loss of 1–2 seconds sometimes occurs during stateful SRP
switchovers.
Subscriber Management
z
When a dynamic GRE tunnel interface for Mobile IP relocates between SM modules
because the original SM reloads, Mobile IP deletes the relocated tunnel interface.
