Vlan tagging is commonly called by Cisco as trunks.
Have you ever configured trunks as ISL ou 802.1q ?
Actually the name vlan tagging makes more sense on non Cisco equipment,
where only exists 802.1q .
ISL doesn't do tag as 802.1q , but reencapsulates the packet with a new
header .

Another option is to use one router ethernet interface per VLAN although

Lo,
Dynamic VLANs are based on MAC address, so a PC with one NIC will have
one MAC even if you have two IP addresses configured on it. The switch
will put the PC in the correct VLAN based on its database.
The PC will end up in one VLAN, and as such will only be able to
communicate with one
Dear All,
Suppose there is a PC have 2 IP address configured in single NIC (10.x,
20.x) and connect catalyst 35xx switch that configured with dynamic vlan.
(NOT tagged)
And there are 2 servers with IP 10.x and 20.x connected to the same switch
as well. The server belongs to VLAN 10 and VLAN 20
VLANs are a layer two construct. The ip address assigned to a switch is used
for management purposes only. So, configure one VLAN as the management VLAN
- default is 1 - give it an ip address, configure an ip default-gateway
and you are set. You can never have more than one Interface VLAN active

Ok Karen,Let me make sure I understand you correctly.thank you for your help
in advanced
This config is what I have on the switch,I have no VLAN attached to it.
I understand all your point except your second one.I thought ISL was
programmed on the router end and not in the switch.I do have
I have a 6509 switch with Cisco IOS in it. I have created a sepearte VLAN
for the managment purpose, and the only way to bring the Managment VLAN up
to assign a port to the VLAN. In most designs, that is not a problem since
there are other IDF switches connected to the backbone switch
of the switch with a straight
through
cable that is connected to
Fast Ethernet 0/0 of the router.I am also using ISL.
On the switch I am using port 1-16 on VLAN 3 and ports 17-24 on
VLAN 10
Workstation 2 is connected to port 17 which is on VLAN 10
Workstation 1 is connected to port 3 which
sing ISL.
On the switch I am using port 1-16 on VLAN 3 and ports 17-24 on
VLAN 10
Workstation 2 is connected to port 17 which is on VLAN 10
Workstation 1 is connected to port 3 which is on VLAN 3

Emile,
Here's what I see right off hand...
1) You aren't trunking. The switch isn't set up for it.
Pick a port to connect the switch to the router with and configure it to
trunk. Make sure that it isn't set up with a VLAN as this can interfer witht
eh trunking.
Example, if you want FE0/1
a network statement for 192.168.0.0
but not for 192.168.1.0

I am having a problem getting two VLANS to work.Help, I
mode multi it will move the VLANS but
raises hell since the MTU is off and there is packet loss.
To fix that scenario I use siwtchport mode trunk to get the right MTU. But
my problem is this..in trunk mode the defualt VLAN, VLAN 1 is automatically
included. I have tried to remove it (switchport
To my knowledge, the IOS based switches I have in my
network, the vlan 1
can't be removed from the trunks, in the case of
2924/2950/3524...

also assign the port1 - port4 to a single vlan v1
the vlan v1 has ip 1.1.2.1/24
I enable protocol vrrp on the vlan v1
Vrrp protocol packet was send from port1-4
However , because the four ports send multicast packet,
the packet length changed ,increase and then decrease.
I do not know
If you use the web interface you can.

individually?
