Hi,

1) I have a lab
2) It is a configuration of the Cisco Router 2600
3) The existing configuration:
- There are Native VLAN (Vlan 1), VLan 10 and Vlan 20
- Please see the attached files
4)The IP of the VLAN 1 is 192.168.1.33 (SM: 255.255.255.224)
- So, This VLan 1 is located at Subnet: 192.168.1.33 - 192.168.1.62
5) I setup a PC, and give the IP within the above subnet; the setup is as the followings:
- IP address of the PC: 192.168.1.34
- The SM: 255.255.255.224
- The Default Gateway: Blank
- The DNS: 192.168.1.34
6) My Goal: I want to get connection between the PC and the Router (I connect the PC and the Router with the cross-over cable)
7) Problems:
- When I open the Command prompts ...
- I ping the Router --> I ping 192.168.1.33 ...
- It does not work; no connection
8) I attach the existing configuration of the router
9) Any help?
10) Thanks

R1(config)#interface ethernet0/0.1
R1(config-if)#encapsulation dot1q 1 native
R1(config-if)#no ip address 192.168.1.33 255.255.255.224
R1(config-if)#exit
R1(config)#no interface ethernet0/0.1
R1(config)#interface ethernet0/0
R1(config-if)#ip address 192.168.1.33 255.255.255.224

>R1(config-if)#half-duplex?
Upon re-reading your existing config, you may want to set this to duplex auto
R1(config-if)#duplex auto

The rest of it is OK.

1) It is possible that the above configuration does not have "No Shutdown"?
2) Is it related to Protocol? explain a little bit related to it Please
3) How to check whether the configuration has got "No Shutdown?"

1) you will not see "no shutdown" in the config
2) it is related to administratively enabling or disabling the entire port
3) R1#show ip interface brief
Here's an example with one interface shutdown and all others "no shut". They should show "up / up"

Loopback0                  192.168.124.1   YES NVRAM  up                    up
Loopback1                  192.168.125.1   YES NVRAM  up                    up
Loopback2                  192.168.125.2   YES NVRAM  administratively down down

lrmoore,

1) This is starting  to get interesting ..

2) When i execute the above commands "show ip interface brief"

3) The results are as the followings:

Ethernet0/0         unassigned        Yes   NVRAM   UP   UP

Ethernet0/0.1      192.168.1.33      Yes   NVRAM   UP   UP

Ethernet0/0.10    192.168.1.65      Yes   NVRAM   UP   UP

Ethernet0/0.20    192.168.1.97      Yes   NVRAM   UP   UP    

4) So, if i just follow your direction above, it should work, right? (I mean i could get the connection between the PC and the Router; then, i can copy the flash from the router to the PC with the help of tftp server)

5 Any other guidance (related to this) is welcome and appreciated

6) Thank you

tjie
