Guidelines for Configuring Stateful Line Module Switchover

70
Stateful SRP switchover is supported on all E120 and E320 routers that contain ES2 4G
line modules installed with the ES2-ES1 Service IOA. See the E120 and E320 Module Guide
for modules supported on the E120 and E320 Broadband Services Routers.
Table 15 on page 70 lists the line module, SRP module, and IOA slot combinations that
support stateful switchover of line modules and stateful switchover for LNS sessions,
when the router operates as an LNS device on one side of an L2TP tunnel.
Number of Active and
Standby ES2-ES1 Service
IOAs
2 Service IOAs (1 active and
1 standby)
4 Service IOAs (2 active and
