    The IRM2 will simultaneously poll all addresses on each circuit’s list; if it cannot establish a link with any address on the list after the designated number of retries, the IRM2 assumes the circuit is down and switches traffic to a designated backup port.

  • Page 77: Assigning Backup Ports And Port Priority To The Circuit

    Each circuit contains one primary port and several additional ports that serve as backups. If the primary port fails, the redundancy path will switch to the first backup port specified, and as necessary, switch to subsequent backup ports in the order in which they were specified.

    If you are polling devices that are some distance from the IRM2, or if your network is somewhat slow, be sure to set your polling interval and/or number of retries accordingly NOTE to avoid the unnecessary use of backup ports.
