VLAN over 1GB Ethernet

Niel Greeff — Tue, 08 Oct 2002 05:40:15 GMT

We have VLAN Info sent accross a 1GB link (from a switch). Any ideas if the 1000 Base-T will handle VLAN ? Will it handle it with the port set at 100MB (on the switch) ?

What I've noticed, is that we pick up a lot of unknown protocol errors (using lanadmin to display), but no traffic !!

Thanks

Well, did a bit of reading on some white papers.

Here are the answers for those who want to know:

VLANs are possible over 1GB or 100BaseT NICs, but only on HP-UX 11i (or 11.11).

Install the following patches:
PHNE_25644
PHNE_23465 (for 100Base T)
PHNE_24491 (for 1GB)
PHNE_27443
PHNE_25388 (core network)

Optional SAM patch
PHCO_25866

Next use either SAM (Networks->VLAN) or edit the /etc/rc.config.d/vlanconf file as follows:

VLAN_PHY_INTERFACE[0]=lan0
VLAN_ID[0]=1 (or whatever the vlan id is set on the switch)
VLAN_PRIORITY[0]=0
VLAN_TOS[0]=0
VLAN_PRI_OVERRIDE[0]=CONF_PRI
VLAN_TOS_OVERRIDE[0]=IP_HEADER
VLAN_NAME[0]=MyVLAN
VLAN_VPPA[0]=5000 (must be above 4999)

If you want more VLANS, just continue with this.

Now you will have a Virtual PPA with number 5000 (or whatever you set it as) and can configure this as per normal.

This will take effect next time you reboot (or restart networking). You can use "lanadmin -V" to set all the settings, but it will be lost on reboot. (Yep the patches updates the man pages with the -V option
