SNMP ASN.01 BER Padding—CR00016523 99

SNMP ASN.01 BER Padding—CR00016523

This enhancement enables you to specify whether SNMP adds 0x00 padding when the most significant 9 bits of an object’s value are all 1, or whether the encoding follows the ASN.01 BER rule, which cuts off the most significant byte of 0xff. This setting has an impact on all integer type MIB objects, including 32 bit and 64 bit counter objects.

To add the padding, use the command:

set snmp asnberpadding={onyestrue}

To use the ASN.01 BER rule, which is the default, use the command:

set snmp asnberpadding={offnofalse}

The following table lists examples.

Bits	Value (decimal)	Value (hex)	asnberpadding setting	Encoding
counter32	4289592837	0xFFADFE05	on	41 05 00 ff ad fe 05
			off	41 03 ad fe 05
counter64	18410715280977201498	0xFF800000ff80895A	on	46 09 00 ff 80 00 00 ff 80 89 5a
			off	46 07 80 00 00 ff 80 89 5a

To see whether or not padding is added, use the command:

show snmp

and check the new “ASN.01 BER Padding” field.
