Description: A bit string representing the software feature of the running switch/router image. These features were conditional compiled to different product images. For each bit, exist feature has a value of 1, but non-exist feature has a value of 0. octet 0, bit 0 - RMON octet 0, bit 1 - ipx switching octet 0, bit 2 - server load balancing octet 0, bit 3 - layer 3 filter in switch octet 0, bit 4 - ipx routing octet 0, bit 5 - appletalk routing octet 0, bit 6 - ip multicast routing octet 0, bit 7 - local access control octet 1, bit 0 - BGP routing octet 1, bit 1 - loopback interface octet 1, bit 2 - BigIron multi-management module octet 1, bit 3 - BigIron SYSIF II octet 1, bit 4 - BigIron POS support octet 1, bit 5 - appletalk cable vlan octet 1, bit 6 - 64 subnet octet 1, bit 7 - multi-slot trunk octet 2, bit 0 - TACACS octet 2, bit 1 - Gigabit Ethernet port auto-negotiation mode octet 2, bit 2 - FSRP octet 2, bit 3 - Exodus requested OSPF enhancement octet 2, bit 4 - OSPF NSSA octet 2, bit 5 - POS octet 2, bit 6 - QOS octet 2, bit 7 - Single Span octet 3, bit 0 - Fast Span octet 3, bit 1 - Base L3 octet 3, bit 2 - static log buffer Bit 0 is the least significant bit of an octet, and bit 7 is the most significant bit of an octet.
