nwAppnExtIfDfltSecurity

Module: CTRON-APPN-MIB

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

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.20

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specify one of the following security selections:

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 nwAppnExtIfDfltSecurity?

This read-write enumeration sets the default security classification for links on this port, choosing among levels such as nonsecure(1), publicSwitchNw(32), undergroundCable(64), and secureConduit. APPN's COS-based routing can use this security level as a criterion, so mismarking a port can cause security-sensitive sessions to route over it inappropriately, or avoid it unnecessarily. An admin with a port riding a public switched carrier circuit would set this to publicSwitchNw(32) rather than a falsely reassuring secure setting.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.20
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfDfltSecurity

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.20.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfDfltSecurity.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.20.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> nwAppnExtIfDfltSecurity.1
