CR00024244 PPP 2 The router or switch would silently discard echo-requests from a PPP peer

after the peer had negotiated with it not to use the LCP magic number

option. This was because the router or switch would discard echo-requests

with a magic number set to 0 regardless of whether the magic number was

required for the link. The magic number option is used to check that the

link is not in loopback mode.

This issue has been resolved. Echo-Requests with a magic number of 0 are

now replied to if the PPP peers have negotiated not to use the LCP magic

number option.

CR00020319 SNMP 3 ASN.01 BER padding is now enabled by default. This means that SNMP

adds 0x00 padding when the most significant 9 bits of an object’s value are

all 1. Padding enables legacy SNMP NMS systems to correctly decode this

value, and provide correct readings.

Previously the default was for the encoding to follow 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 remove the padding, and return to using the ASN.01 BER encoding rule,

use the command:

set snmp asnberpadding={off|no|false}
