Emad,
1. In your config on fa0/9 change the mode to "switchport mode access"
or you may have problems in some versions of switch software or if you
configure DLSw+ on a router connected to this port. Here is your config
from a previous post:
interface FastEthernet0/9
switchport access vlan 2
switchport mode dynamic desirable <== NOT RECOMMENDED TO LEAVE IN
DEFAULT MODE
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12114ea1/3550s
cg/swvlan.htm#1036007
Here's a brief excerpt:
Step 1 configure terminal
Step 2 interface interface-id
Step 3 switchport mode access
Step 4 switchport access vlan vlan-id
Step 5 end
2. Here is a simple config that routes between VLANs. If you are not
using a routing protocol (e.g., OSPF) then typing the command "ip
routing" is NOT necessary.
Ports fa0/19 on the two switches are connected with a crossover cable
which serves as an ISL trunk.
==========
S1_3550#sh run | begin 0/19
interface FastEthernet0/19
switchport trunk encapsulation isl
switchport mode trunk
no ip address
!
interface Vlan2
ip address 20.1.1.1 255.255.255.0
!
interface Vlan3
ip address 30.1.1.1 255.255.255.0
!
ip default-gateway 20.1.1.2
==========
S2_3550#sh run | begin 0/19
interface FastEthernet0/19
switchport trunk encapsulation isl
switchport mode trunk
no ip address
!
<snip>
interface Vlan2
ip address 20.1.1.2 255.255.255.0
!
interface Vlan4
ip address 40.1.1.2 255.255.255.0
!
ip default-gateway 20.1.1.1
==========
The only other commands I typed that are not shown in the excerpted
configs above are these:
==========
vtp domain cisco (on each switch)
vlan 2 (to create the vlan)
vlan 3 (to create the vlan)
vlan 4 (to create the vlan)
==========
Here are the ping tets:
==========
S1_3550#sh ip int brief | include Vlan
Vlan1 unassigned YES unset administratively
down down
Vlan2 20.1.1.1 YES manual up
up
Vlan3 30.1.1.1 YES manual up
up
S1_3550#p 40.1.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 40.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
S1_3550#
==========
S2_3550#sh ip int brief | include Vlan
Vlan1 unassigned YES unset administratively
down down
Vlan2 20.1.1.2 YES manual up
up
Vlan4 40.1.1.2 YES manual up
up
S2_3550#p 30.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 30.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
S2_3550#
==========
I hope this is of use to you. I learned a thing or two myself while
playing around with this. I will put this in a separate post.
Jonathan
