INFO: Initialising Flash (This may take some time)

The flash file system was found to be corrupt. The router is now re- initialising the flash device to a "good" state. The process will take at least 4 minutes, depending on the router.

INFO: IGMP Snooping is activated.

IGMP snooping has been enabled.

INFO: IGMP packet trapping is active for IGMP snooping, L3FILT is activated

IGMP snooping has been enabled.

WARNING: IGMP Snooping not active, failed to enable ports.

The IGMP snooping could not be activated on the switch ports. This may indicate a hardware failure. Contact your authorised Allied Telesis distributor or reseller.

ERR: Error (3035012): Parameter "firewall" not recognised.

The configuration file contains commands not recognised by the software version that is loaded. In the example above, the configuration file contains commands to configure a firewall, but the software does not include the firewall feature - it may be the minimal boot version.

Memory

The routers have memory in the form of:

“Random Access Memory (RAM)” on page 37

“Battery-Backed RAM (AR725, AR745, AR770S only)” on page 39

“Onboard Flash Memory” on page 39

“CompactFlash (AR725, AR745 only)” on page 41

Random Access Memory (RAM)

The routers use RAM to run software for router operations, and to store the router’s dynamic configuration.

The AR725 and AR745 routers have 128 MB of SDRAM on a DIMM and can be upgraded. Contact your authorised Allied Telesis distributor or reseller for upgrade options. Other supplier’s DIMMs are not approved, not supported, and may not function correctly.

!Warning DIMMs should be installed by authorised service personnel only. Unauthorised opening of the router lid may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty.

The AR750S and AR750S-DP routers have 64 MB of DDR SDRAM, and cannot be upgraded.

The AR770S has 128 MB of DDR SDRAM, and cannot be upgraded.

To check the amount of RAM present in a router, use the command:
