Interfaces group
2
ifIndex
1.3.6.1.2.1.2.2.1.1
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
ifDescr
1.3.6.1.2.1.2.2.1.2
Read only 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 <slot/port>
ifType
1.3.6.1.2.1.2.2.1.3
Read only 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
ifMtu
1.3.6.1.2.1.2.2.1.4
Read only 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
ifSpeed
1.3.6.1.2.1.2.2.1.5
Read only An estimate (in bits per second) of the interface's current bandwidth.
For interfaces that do not vary in bandwidth or interfaces for which no
accurate estimation can be made, this object should contain the nominal
bandwidth. For Fabric OS v4.x, 2 Gbps returns.
• eth0 returns 100000000 and not null
• fc port returns 1,000,000,000 for 1 Gbps port
• fc port returns 2000000000 for 2 Gbps port
• fc port returns 4000000000 for 4 Gbps port
• For 10G, value displayed is 4294967295
• For 8G, value displayed is 4294967295
• For 16G, value displayed is 4294967295
