Chapter 2 Catalyst 2950 and 2955 Cisco IOS Commands
switchport access
• The software implements the VLAN Query Protocol (VQP) client, which can query a VMPS such
as a Catalyst 6000 series switch. The VMPS server must be configured before a port is configured
as dynamic.
• Use dynamic-access ports only to connect end stations. Connecting them to switches or routers that
use bridging protocols can cause a loss of connectivity.
• Configure the network so that Spanning Tree Protocol (STP) does not put the dynamic-access port
in an STP blocking state. The Port Fast feature is automatically enabled on dynamic-access ports.
• Dynamic-access ports can only be in one VLAN and do not use VLAN tagging.
• Dynamic-access ports cannot be configured as:
–
Members of an EtherChannel port group (dynamic-access ports cannot be grouped with any
other port, including other dynamic ports).
–
Source or destination ports in a static address entry.
–
Monitor ports.
Examples This example shows how to assign a port already in access mode to VLAN 2 (instead of the default
VLAN 1):
Switch(config-if)# switchport access vlan 2
You can verify your settings by entering the show interfaces interface-id switchport privileged EXEC
command and examining information in the Administrative Mode and Operational Mode rows.
