P-202H Plus v2 Support Notes
< Example >
1. Clear the error counter and display it to verify all counters are 0.
P2864> ip route errcnt cl
P2864> ip route errcnt dis
last route error code = 0
ipRouteFail_Disable 0 ipRouteFail_PktLen 0
ipRouteFail_Header 0 ipRouteFail_CkSum 0
ipRouteFail_OptLen 0 ipRouteFail_OptSRoute 0
ipRouteFail_OptSSRoute 0 ipRouteFail_OptRRoute 0
ipRouteFail_TTL 0 ipRouteFail_No_Route 0
ipRouteFail_Wan_Route 0 ipRouteFail_RnNull 0
ipRouteFail_DF 0 ipRouteFail_Fragment 0
2. Display the IP routing table, and check the 'Use' field for the 'problem' route.
We assume that we are troubleshooting the route to 100.1.1.1 and trying to figure
out why the call was not triggered to the remote node.

204.247.203.191 00 32 enif0 204.247.203.183 1 0015 0 0

100.0.0.0 00 8 wanIdle 100.1.1.1 2 0023 0 0
default 00 0 wanIdle Internet 2 0023 0 0
3. Do a PING to that remote node (IP address 100.1.1.1) from the P-202H Plus
v2 directly. ( You can do it from the LAN also. ) Check the routing table again
306Z> ip ping 100.1.1.1
Resolving 100.1.1.1... 100.1.1.1

306Z> ip route st
Dest FF Len Interface Gateway Metric stat Timer Use
204.247.203.191 00 32 enif0 204.247.203.183 1 0015 0 0
204.247.203.128 00 26 wanIdle 204.247.203.167 2 0023 0 0
100.0.0.0 00 8 wanIdle 100.1.1.1 2 0023 0 3
default 00 0 wanIdle Internet 2 0023 0 0
We can see the 'Use' increased from 0 to 3. This is correct, since each 'ip ping'
command will try to send 3 packets. So no problem in IP routing.
