rxFlowCtrlCollCounter

Module: ETH-SWITCH-MIB

OID (symbolic): ETH-SWITCH-MIB::rxFlowCtrlCollCounter

OID (numeric): 1.3.6.1.4.1.208.39.4.2.1.47

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: This counter counts the number of Flow Control collisions, which are generated due to flow control. Flow control are used when most of the pool memory are used to limit further amount of RX data until memory available.

What is rxFlowCtrlCollCounter?

Counts collisions the switch deliberately generates as a flow-control mechanism, jamming the shared segment to make senders back off once most of the switch's packet-buffer pool memory is in use. A rising count is a sign the switch itself is running low on buffer memory, not a wiring problem.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.208.39.4.2.1.47
snmpwalk -v2c -c public <target> ETH-SWITCH-MIB::rxFlowCtrlCollCounter

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.208.39.4.2.1.47.1
snmpget -v2c -c public <target> ETH-SWITCH-MIB::rxFlowCtrlCollCounter.1
