Description: This attribute indicates the number of uncompressed bytes divided by the number of compressed bytes. A value greater than one means that the data is being compressed. This is the compression ratio achieved by the V.42bis encoder running on the Passport. This attribute is relevant for both protocol modes transparent and compressed as the encoder switches between the two modes.

What is gsmBcV42bisCompRatioEncoder?

The compression ratio (uncompressed bytes / compressed bytes) this bearer channel's V.42bis encoder is currently achieving on the Passport side; a value above 1 confirms data is actually being compressed, and operators use it to judge whether compression is paying off for the traffic on this specific call.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.128.9.10.1.7
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-GsmIwfMIB::gsmBcV42bisCompRatioEncoder

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.128.9.10.1.7.1
