Chapter 2 Catalyst 3750 Switch Cisco IOS Commands
switchport access
These restrictions apply to dynamic-access ports:
• The software implements the VLAN Query Protocol (VQP) client, which can query a VMPS such
as a Catalyst 6000 series switch. The Catalyst 2960 switches are not VMPS servers. 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 STP does not put the dynamic-access port into 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 change a switched port interface that is operating in access mode to operate
in VLAN 2 instead of the default VLAN:
Switch(config-if)# switchport access vlan 2
You can verify your setting by entering the show interfaces interface-id switchport privileged EXEC
command and examining information in the Administrative Mode and Operational Mode rows.
