ctEtherSupportedSpeed
Module: CTRON-ETHERNET-PARAMETERS-MIB
OID (symbolic): CTRON-ETHERNET-PARAMETERS-MIB::ctEtherSupportedSpeed
OID (numeric): 1.3.6.1.4.1.52.4.1.2.4.2.3.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This indicates the supported speeds for the port.
The value is a sum. This sum initially takes the value zero. Then, for each speed, S, that the port supports, 2 raised to (S - 1) is added to the sum. For example, a port that supports 10 Mb (S = 1) and 100 Mb (S = 2) would return a value of 3 ((2 ^ (1 - 1)) + (2 ^ (2 - 1))).
Speed values should be calculated as follows:
S Speed Description -- ----------- ------------------------------------------------ 1 10 Mb Ethernet 2 100 Mb Fast Ethernet 3 1000 Mb Gigabit Ethernet
What is ctEtherSupportedSpeed?
This is a bitmask-encoded sum indicating which Ethernet speeds, such as 10Mb or 100Mb, this port's hardware is capable of operating at. It tells an admin the ceiling of what speed configuration is even possible on that port before attempting to set it. For example, a value of 3 decodes to support for both 10Mb and 100Mb, confirming this is a Fast Ethernet port rather than a gigabit-capable one.
