1. An IP interface is a physical or logical interface (e.g. ATM PVC, PPP session, VLAN, IP inter-
face in a bridge group) which is configured for IP traffic (routed mode) and is not in the admin-
istrative
down
status. The loopback interfaces (
softwareLoopback
and
usrLoopback
) are
excluded. An IP interface is up if its operational status is
up
or
dormant
(interface is up on layer
2 and it has either obtained a dynamic IP address (e.g. from IPCP or DHCP) or a static IP
address is configured. The status of loopback interfaces is ignored.
2. The above definition means that the IP LED will function as soon as the device is IP manage-
able or it has any active routed interfaces.
