Module: CADANT-CMTS-DOWNCHANNEL-MIB

OID (symbolic): CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDownChannelInterleave

Type: INTEGER

Access: read-write

Description: The Forward Error Correction (FEC) interleaving used for this downstream channel. Values are defined as follows: taps8Increment16(3): protection 5.9/4.1 usec, latency .22/.15 msec taps16Increment8(4): protection 12/8.2 usec, latency .48/.33 msec taps32Increment4(5): protection 24/16 usec, latency .98/.68 msec taps64Increment2(6): protection 47/33 usec, latency 2/1.4 msec taps128Increment1(7): protection 95/66 usec, latency 4/2.8 msec taps12increment17(8): protection 18/14 usec, latency 0.43/0.32 msec If the interface is down, this object either returns the configured value (CMTS), the most current value (CM), or the value of unknown(1). The value of other(2) is returned if the interleave is known but not defined in the above list. See the associated conformance object for write conditions and limitations. See the reference for the FEC configuration described by the setting of this object. non RFC 2670 interleave modes are only available for annex B.

What is cadIfDownChannelInterleave?

Reports or configures the Forward Error Correction (FEC) interleaving depth for a downstream channel, balancing burst-error protection against transmission latency. Deeper interleaving improves robustness to noise bursts at the cost of increased delay.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.15.2.1.1.5
snmpwalk -v2c -c public <target> CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDownChannelInterleave

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.15.2.1.1.5.1
snmpget -v2c -c public <target> CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDownChannelInterleave.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4998.1.1.15.2.1.1.5.1 i <value>
