ewnMirrorAvailablePortMap
Module: EtherWAN-ewnSwitchM
OID (symbolic): EtherWAN-ewnSwitchM::ewnMirrorAvailablePortMap
OID (numeric): 1.3.6.1.4.1.2736.1.1.3.1
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: A bitmap of ports, with each bit indicating availability of a port to be a candidate for mirrored port. For example, if fe3 is mirrored-to port, and fe9 is mirrored port. This object would have a value of 'DF 7F C0' (in hex), assuming the device has 18 ports.: Octet Bits Ports -------- ----------- --------------------------------------- DF 1101 1111 Port 3(fe3) is not available 7F 0111 1111 Port 9(fe9) is not available C0 1100 0000 Port 17(ge1),18(ge2) are available Note that bit 7 of the first octet (value of 0xDF) represents port 1 (fe1).
What is ewnMirrorAvailablePortMap?
A bitmap where each bit flags whether a port is available to be configured as a mirror source or destination; per the MIB's own example, a value of 'DF 7F C0' on an 18-port switch means ports 3 and 9 are unavailable (already in use as mirror ports) while ports 17-18 are available.
