pportDS0SwitchLpbkStart

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::pportDS0SwitchLpbkStart

OID (numeric): 1.3.6.1.4.1.277.1.4.2.1.99

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This is the first DS0 in a sting of consecutive DS0's to be looped back at the switch if the DS0 processor is set to switch loopback. If it's set to far end loopback, this determines which singleton DS0 will be monitored at the receive end.

What is pportDS0SwitchLpbkStart?

This identifies the first DS0 in a consecutive range to be looped back at the switch when pportDS0LpbkMode is set to switch loopback, or, in far-end loopback mode, the single DS0 to be monitored at the receive end. This object's meaning literally changes depending on the current loopback mode on this port, so misreading which mode is active before interpreting this value on this specific channel would lead to testing, or monitoring, the wrong set of DS0s entirely. In switch-loopback mode with this set to 5 and pportDS0SwitchLpbkEnd set to 9, DS0 channels 5 through 8 on this port would be looped at the switch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.99
snmpwalk -v2c -c public <target> CASCADE-MIB::pportDS0SwitchLpbkStart

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.99.1
snmpget -v2c -c public <target> CASCADE-MIB::pportDS0SwitchLpbkStart.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.99.1 i <value>
