The value of tmnxIPMafMatchSrcPortType is used, in conjunction with the value of tmnxIPMafMatchSrcPortId, to specify the type of port that applies to the management access filter entry. By default, management traffic is accepted on all interfaces. If the value of tmnxIPMafMatchSrcPortType is equal to any(1), the default, then no filtering is done on ingress management packets. If the value of tmnxIPMafMatchSrcPortType is equal to cpm(2) then the filter applies to packets received on any CPM/CCM Ethernet port. If the value of tmnxIPMafMatchSrcPortType is equal to port(3) or lag(4) then the filter applies to the packets received on the port or lag specified by the value of tmnxIPMafMatchSrcPortId. The value of tmnxIPMafMatchSrcPortId can be set to other value then 503316480 (INVALID_PORT) only if the value of tmnxIPMafMatchSrcPortType is port (3) or lag (4). In summary, the valid configurations are: src-port-type src-port-id Meaning any(1) INVALID_PORT No filtering cpm(2) INVALID_PORT Match packets received on any CPM/CCM Ethernet port port(3) port-id Match packets received on specified port lag(4) lag-id Match packets received on specified lag If tmnxIPMafMatchSrcPortType is any(1) or is set to any(1) then any change to tmnxIPMafMatchSrcPortId is ignored and its value is forced to 503316480 (INVALID_PORT) by the system. When tmnxIPMafMatchSrcPortType is set to cpm(2), cpm1(5), cpm3(6), cpm4(7) then the value of tmnxIPMafMatchSrcPortId, if specified, is ignored and forced to 503316480 (INVALID_PORT) by the system. When the value of tmnxIPMafMatchSrcPortType is set to port(3) or lag(4) then tmnxIPMafMatchSrcPortId must specify a valid port-id or lag-id, otherwise the request is rejected by the system. Note that the port-type is always subordinate to the port-id, i.e. if the value of tmnxIPMafMatchSrcPortType is set to port(3) and at the same time the value of tmnxIPMafMatchSrcPortId is set to a lag-id the the system will accept the lag-id and silently set the value of tmnxIPMafMatchSrcPortType lag(4) (or vice versa).
