Troubleshooting TCP/IP Connectivity
When different access lists are configured on the router, the show ip
access-list
command shows NAMED IP access lists only. From the
following sample output, you can see that it lists both standard and
extended lists:
Standard IP access list 5
permit 172.16.14.2
permit 172.16.91.140
permit 172.16.10.51
permit 172.16.1.7
permit 172.16.155.0, wildcard bits 0.0.0.255
Extended IP access list 152
deny ip any 172.16.91.0 0.0.0.63 log (268436 matches)
deny ip any host 172.16.91.66 log (81058 matches)
permit tcp any any established (8809 matches)
permit ip host 172.16.2.55 any
permit ip host 172.60.22.10 any (2194226 matches)
permit ip host 172.140.64.8 any (7930443 matches)
permit ip 172.16.10.0 0.0.255.255 any (9076 matches)
show ip protocols
This command provides information about the IP
routing protocols that run on the router. The sample output includes only
EIGRP information because that is all that is being run on the router. As
you can see, global filters are not applied. Metric values are displayed for
each individual routing protocol. Route redistribution information is also
provided.
Router_B#show ip protocols
Routing Protocol is "eigrp 100"
Outgoing update filter list for all interfaces is not
set
Incoming update filter list for all interfaces is not
set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
