s5EnPortExtHwCapability

Module: S5-ETHERNET-COMMON-MIB

OID (symbolic): S5-ETHERNET-COMMON-MIB::s5EnPortExtHwCapability

OID (numeric): 1.3.6.1.4.1.45.1.6.6.1.3.1.3

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: A bit array that contains the bit map representing the hardware capabilites of the port. The bit 7 tells if the port supports auto-negotiation. If the auto negotiation is on, the port will have multiple speed capabilities while if the auto negotiation is not supported, the hardware will only be capable for one speed:

bit 0 - 10 BASE-T half duplex capable bit 1 - 10 BASE-T full duplex capable bit 2 - 100 BASE-TX half duplex capable bit 3 - 100 BASE-TX full duplex capable

bit 5 - 100 BASE-FX full duplex capable bit 6 - 100 BASE-FX half duplex capable bit 7 - auto negotiation support capability

When auto negotiation is supported only bits 0-3 are used to indicate the capabilities available for negotiation, and any or all of these bits may be set as long as at least one bit is set.

When auto negotiation is NOT supported (bit 7 = 0) all other bits are used to indicate the capabilities supported by the port, but which must be manually configured.

What is s5EnPortExtHwCapability?

A bitmap of this port's hardware speed/duplex capabilities (10/100 Mbps, half/full duplex) and whether it supports auto-negotiation at all (bit 7); when auto-negotiation isn't supported, the remaining bits show the single fixed speed/duplex the hardware must be manually configured for.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.1.6.6.1.3.1.3
snmpwalk -v2c -c public <target> S5-ETHERNET-COMMON-MIB::s5EnPortExtHwCapability

Get a specific instance (index 1):
