Stateful SRP Switchover (High Availability) and IP Tunnels
Subscriber Interfaces

System
A memory leak of about two percent can occur on the ES2 10G LM and result in
a module reset when a large number of successive SRP switchovers take place
with active DHCP clients. [Defect ID 86245]
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]
After a stateful SRP switchover, forwarding of VPN traffic might not resume if
the core interface that carries an MPLS base tunnel with LDP over RSVP-TE
flaps (constantly goes up and down). [Defect ID 182019]
When you change the demultiplexer type on a primary interface that has 1024
demultiplexer table entries, the ICC ping threshold times out due to the
removal of the old entries and the addition of the new ones. [Defect ID 175029/
182218]
The ES2 10G LM does not support framed routes configured for dynamic
subscriber interfaces. [Defect ID 83154]
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 the major Ethernet interface is bounced, the dynamic VLAN interfaces
are removed but the dynamic subscriber interfaces remain in the down/not
present state even after the DHCP client renegotiates the same IP address from
the DHCP server. [Defect ID 81269]
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.
You cannot use a configuration script to boot the E320 router. [Defect ID
80304]
If you hot swap an IOA and then remove it again before that IOA's OK or FAIL
LED is illuminated, the associated line module can reset. [Defect ID
177313/177267]
Work-around: Ensure that you firmly insert the IOA into the chassis when you
hot swap IOAs. Do not attempt a second hot swap of an IOA that has not
indicated that it completed the first hot swap cycle. You can remove the IOA
when either its OK or FAIL LED is illuminated.
