1. bad hop count: Occurs when a packet is discarded because its time-to-live (TTL) field was decremented to zero.
2. not a gateway count: ???
3. encapsulation failed count: Usually indicates that the router had no ARP request entry and therefore did not send a datagram.
4. no route count: Counted when the Cisco IOS software discards a datagram it did not know how to route.
I woudn't worry very much about bad hop and encapsulation failed. About no route count I'm not sure but I think maybe some machine(s) in your network is trying to access a network your router don't know. So you can check your routing configuration or try to block undesired traffic before reaching your router
um could i ask something.. coz the values above are fast increasing.. how could i minimize them.. and along side.. on my eth.. my deffered counts also increases.. but my excessive and late collisions somehow stay zero.. i want to know the problem because.. what happens to my network is.. some PCs get randomly disconnected from our DB server from the other side of the network..
here's my config and ip route..
no ip domain-lookup
ip address 10.0.1.1 255.255.255.19
no ip route-cache
description Leased Line to Gualo Rai
ip address 10.0.0.1 255.255.255.252
no ip classless
ip route 10.0.2.0 255.255.255.240 10.0.0.2
line con 0
exec-timeout 0 0
line vty 0 4
10.0.0.0/8 is variably subnetted, 3 subnets, 3 masks
I assume the subnet mask on your ethernet is 255.255.255.192, and not .19 as shown.
Make sure all of your hosts on this network are configured with the correct subnet mask i.e. some don't have 255.255.255.0 by mistake. By my calculation, the hosts on this network should range between 10.0.1.1 up to .62 (.63 is the broadcast).
Simarly, all hosts on your 10.0.2.0/28 network should be configured with the 255.255.255.240 SNM. Hosts on this network should be in the range 10.0.2.1 up to 10.0.2.14 (.15 is the broadcast).
(If someone checks my calculations here, I'd be grateful).
Incorrect ip settings, especially subnet mask, can cause unpredictable results.
thanks jolmo, for the explanation of the terms.. really a great help!
thanks CKBudrodeen, for the reminder..
yep.. it's 255.255.255.192.. it's a typo transfer error.. the copy and paste thing =)
all your calculations are right.. 62 Hosts and 14 Hosts (excluding the network and broadcast ip) but only 6 hosts per side are crossing to each other side.. i solved my own prob (reducing the increments) by configuring only the 6 hosts with gateway IPs and hard-coded their IPs and MAC Adds to the router. I don't have a manageable switch so for now that's fine. I just experimented and it seemed ok now.. i dont know.. but it seems =)
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
