Configuring Management Access Filters

Creating and implementing management access filters is optional. Management access filters control all traffic going in to the CPM, including all routing protocols. They apply to packets from all ports. The filters can be used to restrict management of the 7210 SAS router by other nodes outside either specific (sub)networks or through designated ports. By default, there are no filters associated with security options. The management access filter and entries must be explicitly created on each router. These filters also apply to the management Ethernet port.

The 7210 SAS implementation exits the filter when the first match is found and execute the actions according to the specified action. For this reason, entries must be sequenced correctly from most to least explicit.

An entry may not have any match criteria defined (in which case, everything matches) but must have at least the keyword CPM to be considered complete. Entries without the action keyword are considered incomplete and will be rendered inactive.

Use the following syntax to configure a management access filter. This example only accepts packets matching the criteria specified in entries 1 and 2. Non-matching packets are denied.
