Interfaces group 2 TABLE 9 Object and OID Access Description ifIndex 1.3.6.1.2.1.2.2.1.1 ifDescr 1.3.6.1.2.1.2.2.1.2 ifType 1.3.6.1.2.1.2.2.1.3 ifMtu 1.3.6.1.2.1.2.2.1.4 Read only Read only Read only Read only A unique value for each interface. The values range between 1 and the value of ifNumber. The value for each interface must remain constant, at least from one re-initialization of the entity's network management system to the next re-initialization. For Network Interface, the number starts from 805306369 and increments with the interface count. For FC ports, the number starts from 1073741824 and increments with the existing FC ports. Similarly the index value range for the interfaces are as follows: • For GbE port the number starts from 268435456 • For Ten GbE (FCoE ports) the number starts from 402653184 • For FCIP Tunnel the number starts from 536870912 • For xFCIP Tunnel the number starts from 1342177280 • For Port channel the number starts from 671088640 • For VLAN the number starts from 1207959552 A textual string containing information about the interface. The ifDescr for non-bladed switches includes: lo, eth0, and fc0. The ifDescr for Brocade 12000, 24000, and 48000 directors includes: lo, eth0, fc0, and sit0, as well as fc1, eth0:1, and eth0:2. Valid values: • For WAN interface - GbE port for FCIP • For transport interface - FCIP tunnel ID • For FC ports - Port name (if set), otherwise, FC port The type of interface, designated by the physical link protocols immediately below the network layer in the protocol stack. • For WAN interface, FCIP Link - ethernetCsmacd (6) • For transport interface - FCIPLink (224) • For FC ports - Fibre Channel (56) • For lo - softwareLoopback (24) • For sit0 - 131 • For fc0/port0 - other The size of the largest datagram that can be sent or received on the interface, specified in octets. For interfaces that are used to transmit network datagrams, the value is the size of the largest network datagram that can be sent on the interface (these values are different for Fabric OS v4.x). • eth0 returns 1500 • lo returns 16436 • fc0 returns 2024 • FCIP GbE returns 1500 • sit0 returns 1480 • port0 returns 2112 Fabric OS MIB Reference 35 53-1002750-01
