Setup Procurve 3400c for vlan tagging

[ggoyal]

Hi,

I am currently using only 2 ports. both are connected to the same subnet.
One port(port 1) of my switch is connected to internet and another port(port 2) is used for internal purpose.
The output of the port 2 should be a tagged vlan. while output of port 1 is normal ethernet traffic.
Please help me out in configuring my switch

What do you intend to do with your setup? Have some computers directly access the Internet? Route between the subnets you intend to define? In my opinion you lack a firm grasp of the VLAN concept versus the subnet concept.

my hole intension is to generate some vlan tagged pkts. therefore i want one of my ports to output tagged packets. i have one traffic generating machine which can pump data to my switch.

3400(config)# vlan tagged

[ggoyal]

my configuration is
Running configuration:

; J4905A Configuration Editor; Created on release #M.08.74

hostname "HP ProCurve Switch 3400cl-24G"
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-18,21-24
ip address dhcp-bootp
no untagged 17-20
exit

vlan 20
name "VLAN20"
untagged 19
tagged 20
exit


data that is coming out from port 20 does not contain 802.1Q ethernet header. vlan id is not tagged.

[Matt Hobbs]

The data coming out of port 20 will have the 802.1Q tag. Most likely though your NIC is stripping that tag before you can see it. With Intel and Broadcom based NICs you can make some registry changes in order to see the tagged packets.
