IPoE sessions are supported in a Routed CO environment with ESM enabled. To enable the IPoE session instantiation, the ipoe-session CLI context on the capture SAP (managed SAP scenario) and group-interface must be configured to no shutdown. See also the configuration steps below.
Important Notes:
Enabling IPoE sessions on a group-interface with active subscriber hosts triggers a migration. Use one of the following CLI command to determine if there are active hosts on a group interface:
Check the number of subscriber hosts on a group interface:
Note that DHCPv6 IA-PD modeled as a managed route are not counted with this command.
show service id <service-id> subscriber-hosts detail | match <group-int-name> | count
Check the number of IP stacks (Client types) attached on a group-interface. tools dump router <router-instance> ipoe-session migration interface <group-int-name>
The active number of IP stacks (Client types) on the group-interface are listed per type as well as if they are associated with an IPoE session or not.
Note that DHCPv6 IA-PD modeled as a managed route is also counted in the DHCPv6 type counter.
Check the number of DHCPv4 leases, DHCPv6 leases and SLAAC hosts on the group interface that are not attached to a session: show service id <service-id> dhcp4 lease-state interface <group-int-name> session none
show service id <service-id> dhcp6 lease-state interface <group-int-name> session none
show service id <service-id> slaac host interface <group-int-name> session none
DHCPv6 IA-PD modeled as a managed route is also counted in the DHCPv6 lease state counter.
If there are active hosts on the group interface, make sure you have read the ‟IPoE session migration” section before enabling IPoE sessions.
Disabling IPoE sessions by executing an ipoe-session shutdown command or no ipoe-session command on a group interface deletes all active sessions and associated hosts on that group interface, resulting in service impact for these subscribers. Use one of the following CLI commands to determine if there are active ipoe-sessions on a group-interface:
# show service id <service-id> ipoe session interface <group-int-name>
# tools dump router <router-instance> ipoe-session migration interface <ip-int-name>
If there are active IPoE sessions on the group interface, be aware that disabling IPoE sessions on the group-interface results in service impact for those sessions.
