Known Problems and Limitations

Release 10.3.2
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
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. [Defect ID 178399]
When a subscriber has subscribed for a service, service session accounting
records always contains a default Acct-Terminate-Cause value of 10. This value
remains unchanged even after you use the
terminate-code
command to
configure a custom mapping between application terminate reasons and
RADIUS Acct-Terminate-Cause attributes. [Defect ID 181043]
MAC address validation not working for IP auto-detect sessions. [Defect ID
86446]
Dynamic subscriber interfaces continue to remain in the down or not present
operational state in either of the following scenarios: [Defect ID 81269]
If you configured a dynamic interface column, such as a dynamic bridged
Ethernet interface, dynamic VLAN interface, or an ATM interface, and when
any one of the following conditions is satisfied:
The major interface is bounced (shut down and reenabled)
The major interface is shut down, which cause the dynamic VLAN
interfaces to be removed
The physical link goes down and comes back up
The line module is removed and reinserted
If you configured a static interface column and removed the major interface
These scenarios might occur if you administratively issue the
shutdown
and
no
shutdown
commands on the major interface in which the dynamic interface
column is configured.
Work-around
: Use the
no interface ip
ipAddress
command to remove the
dynamic subscriber interfaces. Although you can use the
dhcp delete-binding
command to remove the DHCP binding and the dynamic subscriber interfaces,
the DHCP client does not detect the binding removal and retains the lease.
