• N+1
N Cisco SCE platforms are active and one platform is on standby. The EC ports connected to the standby Cisco SCE
platform must be configured as standby ports. If one Cisco SCE platform fails, the EtherChannel ports connected to the
failing SCE platform are shut and the standby EtherChannel ports, connected to the standby SCE platform are activated.
Because Cisco SCE 8000 supports two links, this configuration requires one SCE platform per two links (two EtherChannel
ports), plus one extra SCE platform for standby.
Note The standby SCE platform must be connected to the two highest-numbered ports, because EC behavior
automatically designates these ports as the standby ports.
Redundant Cisco 7600 Series Router
Two Cisco 7600 Series routers can be used to provide network redundancy (see
In this topology, one link on each Cisco SCE 8000 platform is connected to each router. Therefore, one SCE platform is required
for each link.
