Port-security and VLAN tagged
Posted: 06 Apr 2018 04:09
Hello everyone,
I just have a problem with a Vo-IP phone and port-security. I wish get to know why happens that.
- VoIP phone connected to port 1/3 of switch. PC connected to phone Ethernet port. That's get different IP addresses from DHCP servers separated by VLAN.
If I plug computer or phone separately works fine. So, when I connect both devices at same time, I cannot give IP from DHCP's servers.
I have 2 VLANs set up.
- 39 - Network's group
- 42 - Network phone's group
39 VLAN is set as default for port 1/3:
42 VLAN is tagged using:
Enable port-security:
Using default rule that's assigned 5 Max MAC filtering I don't understand why is not work both devices at same time. Why happen?
However, If I disable port-security, staff can works with both devices, both gives IP and get nice work,
