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:
Code: Select all
vlan 39 port default 1/3
Code: Select all
vlan 42 802.1q 1/3
Code: Select all
port-security 1/3 admin-status enable
However, If I disable port-security, staff can works with both devices, both gives IP and get nice work,
