nwAppnFwdLsSecurity

Module: CTRON-APPN-MIB

OID (symbolic): CTRON-APPN-MIB::nwAppnFwdLsSecurity

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.20

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Security selections available for the link are as follows:

non-secure - specifies no security. public switched - data flows over a public switched network. underground cable - data transmitted over a secure underground cable. secure conduit - line is secure conduit that is not guarded. guarded conduit - conduit that is protected against physical tapping. encrypted - encryption over the line. guarded radiation - line is proected against physical and radiation tapping.

What is nwAppnFwdLsSecurity?

This read-write enumeration sets the security classification of this specific link, choosing among levels such as nonsecure(1), publicSwitchNw(32), undergroundCable(64), and secureConduit(96). COS-based routing can use this per-link value to steer security-sensitive session traffic toward or away from this particular link. An admin whose link rides an underground cable rather than a public switched path would set this to undergroundCable(64) instead of a less secure default.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.20
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsSecurity

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.20.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdLsSecurity.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.3.1.1.1.20.1 i <value>
