1.3 Interface Numbers

IF-MIB contains information about all the interfaces on the switch. Users can access the interface
specific MIB object values using interface index (ifIndex) numbers. The ifIndex numbers are assigned by
switch software for every physical and logical interface. The table below shows ifIndex to interface
mapping method.
Interface Type
1Gig physical interfaces
10Gig physical interfaces
40Gig physical interfaces
Port channel interfaces
Layer 3 interfaces
Starts from 1 and goes up to the maximum number of 1Gig interfaces
available on the switch.
For SSE-G24-TG4, SBM-GEM-X2C, SBM-GEM-X2C+, SBM-GEM-X3S+: 1 to 24
For SSE-G48-TG4: 1 to 48
For SSE-X24S and SBM-XEM-X10S: 1
For SSE-X3348S: 1 to 2
For SSE-X3348T: 1 to 2
Starts after 1Gig ifIndexes and goes up to the maximum number of 10Gig
interfaces available on the switch.
For SSE-G24-TG4, SBM-GEM-X2C, SBM-GEM-X2C+, SBM-GEM-X3S+: 25 to 28
For SSE-G48-TG4: 49 to 52
For SSE-X24S and SBM-XEM-X10S: 2 to 25
For SSE-X3348S: 3 to 50
For SSE-X3348T: 3 to 50
Startsg after 10Gig ifIndexes and goes up to the maximum number of 40Gig
interfaces available on the switch.
For SSE-X3348S: 51 to 54
For SSE-X3348T: 51 to 54
Starts after 10Gig / 40Gig ifIndexes and goes up to the maximum number of
port channel interfaces supported on the switch.
For SSE-G24-TG4, SBM-GEM-X2C, SBM-GEM-X2C+, SBM-GEM-X3S+: 29 to 52
For SSE-G48-TG4: 53 to 76
For SSE-X24S and SBM-XEM-X10S: 26 to 49
For SSE-X3348S: 55 to 78
For SSE-X3348T: 55 to 78
Starts after port channel ifIndexes and goes up to the maximum number of
layer 3 interfaces supported on the switch.
On switch models SSE-G24-TG4, SSE-G48-TG4, SSE-X24S, SSE-X3348S and
SSE-X3348T, the default VLAN 1 and stacking VLAN 4069 takes the first two
layer 3 ifIndexes.
On switch models SBM-GEM-X2C, SBM-GEM-X2C+, SBM-GEM-X3S+ and
SBM-XEM-X10S, the first three layer 3 ifIndexes are assigned for CMM 1 IP
interface, CMM 2 IP interface and stacking VLAN 4069.
User created layer 3 interfaces follow the above ifIndexes.
