radiusDynAuthServCoANaks
Module: RADIUS-DYNAUTH-SERVER-MIB
OID (symbolic): RADIUS-DYNAUTH-SERVER-MIB::radiusDynAuthServCoANaks
OID (numeric): 1.3.6.1.2.1.146.1.2.1.19
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of RADIUS CoA-NAK packets sent to this Dynamic Authorization Client. This includes the RADIUS CoA-NAK packets sent with a Service-Type attribute with value 'Authorize Only' and the RADIUS CoA-NAK packets sent because no session context was found. This counter may experience a discontinuity when the DAS module (re)starts, as indicated by the value of radiusDynAuthServerCounterDiscontinuity.
What is radiusDynAuthServCoANaks?
Counts CoA-NAK replies sent to this client (including Authorize-Only and no-session-context cases); a high value relative to CoA-ACKs suggests many CoA pushes are targeting sessions the server can't modify.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.146.1.2.1.19 snmpwalk -v2c -c public <target> RADIUS-DYNAUTH-SERVER-MIB::radiusDynAuthServCoANaks
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.146.1.2.1.19.1 snmpget -v2c -c public <target> RADIUS-DYNAUTH-SERVER-MIB::radiusDynAuthServCoANaks.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> radiusDynAuthServCoANaks.1
