swL2DevCtrlHOLState
Module: ES1200-MIB
OID (symbolic): ES1200-MIB::swL2DevCtrlHOLState
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.25.2.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The object provides a way to prevent HOL (Head Of Line) blocking between ports. HOL protection may prevent forwarding a packet to a blocking port.The idea relies on the assumption that it is better to discard packets destined to blocking ports, then to let them consume more and more buffers in the input-port's Rx-counters because eventually these input ports may become totally blocked. The meanings of the values are:
other(1) - this entry is currently in use but the conditions under which it will remain so are different from each of the following values. disabled(2) - HOL function disable for device. enabled(3) - HOL function enable for device.
What is swL2DevCtrlHOLState?
A read-write enumeration enabling Head-Of-Line blocking protection device-wide, discarding packets destined to an already-blocked port rather than letting the receiving port's buffers fill up -- the device-wide counterpart to the per-port swL2PortCtrlHOLState.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.25.2.1.1.4 snmpwalk -v2c -c public <target> ES1200-MIB::swL2DevCtrlHOLState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.25.2.1.1.4.1 snmpget -v2c -c public <target> ES1200-MIB::swL2DevCtrlHOLState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.25.2.1.1.4.1 i <value>
