Tagged VLAN Example scenario:
This example illustrates a case where all devices attached to the switch are VLAN unaware, except the ‘feed’
from another switch or router on port 1. All devices on this switch are in VLAN VID=4, which is unique in
a topology that includes multiple switches.
- port 1 accepts and sends only tagged VID=4 frames.
(discards any other incoming - untagged or other tags not 4)
(sends no untagged nor any other tags not 4)
- the other ports ( 2 thru 17) send out only untagged frames.
they accept untagged frames.
they discard frames tagged other than VID=4.
they will accept tagged vid=4 frames (which wouldn’t matter if those devices do not do tagged vlan)
Continued on next sheet….
CLI\SWITCH\VLAN>enable
Tagged VLAN is Enabled.
CLI\SWITCH\VLAN>group2
Configure Tagged VLAN Group 2.
Enter VID or <(ESC)> to exit> 4
Enter ports to Join VLAN Group 2
(Example: '3,6,12,14
Enter Port Numbers (or ESC to exit)> 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17
These ports were removed from group1: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
Would you like all these ports to have PVID=4 ?
Enter 'NO' or (YES):
CLI>
For incoming pkts with tagged VID=4, the outgoing pkts are untagged
for ports: all
Do you want to change this ?
Enter 'YES' or (NO):
CLI>yes
For VID=4 enter ports for outgoing untagged pkts:
(Example: '3,6,12,14
Enter Port Numbers (or ESC to exit)> 2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17
CLI\SWITCH\VLAN>untagged
Tagged VLAN: Handling Untagged Incoming Pkts:
Untagged pkts to these ports are discarded: all
Would you like to change that ? Enter 'YES' or (NO):
CLI>yes
Enter Port Numbers for which to drop incoming untagged pkts
(or just
(or ESC to exit)> 1
