I am developing a user interface for vlan (802.1q) configuration based on SNMP. In each row of the Static Vlan Table, there is "Egress Ports List" and "Untagged Ports List" attributes.

I am quite confused about the related behaviour or impact of these parameters.

  1. If one port's pvid changes from 1 (default_vlan) to 5, should this port also be added into the "Egress Ports List" of VLAN 5? and also the "Untagged Ports List" of VLAN 5?

  2. If a specific row is deleted from the Static Vlan Table (e.g., Vlan 5), what about the port with the pvid of this Vlan? should the user be notified about this, or this pvid will turn to be 1 (default_vlan)?

What platform are you writing this for? I'm not familiar with a "Static Vlan Table". – Aaron Sep 30 '11 at 14:38

WHY are you doing this? Enabling SNMP Write access to systems is generally regarded as a Bad Idea - See any one of thousands of articles around the internet for the reason why... – voretaq7♦ Sep 30 '11 at 14:42
@voretaq7 this is a pretty standard way of enabling a helpdesk to make VLAN changes in large enterprises (usually via a tool that does some sanity checking before SNMP writing). – polynomial Oct 1 '11 at 18:54
I second @Aaron's question. Can you provide more information about the platform being used here? Otherwise this question is unanswerable and should be deleted... – polynomial Oct 1 '11 at 18:56
Hi, guys, thanks for the comments. platform? what is the relationship with platform? This should apply to general cases, right? – pepero Oct 3 '11 at 13:05
