PurposeCommand or Action
Specifying the map name and optionally a number enters the access-map
configuration mode.
Sets the VLAN access map to drop and log IP packets.action drop log
Example:
Switch(config-access-map)# action
Step 3
drop log
Exits the VLAN access map configuration mode and return to the global
configuration mode.
exit
Example:
Switch(config-access-map)# exit
Step 4
Configures the VACL logging parameters.
vlan access-log {maxflow max_number
| threshold pkt_count}
Step 5
• maxflow max_number—Sets the log table size. The content of the log
table can be deleted by setting the maxflow to 0. When the log table
is full, the software drops logged packets from new flows.
Example:
Switch(config)# vlan access-log
The range is from 0 to 2048. The default is 500.
threshold 4000
• threshold pkt_count—Sets the logging threshold. A logging message
is generated if the threshold for a flow is reached before the 5-minute
interval.
The threshold range is from 0 to 2147483647. The default threshold is
0, which means that a syslog message is generated every 5 minutes.
Returns to privileged EXEC mode.end
Example:
Switch(config)# end

Configuration Examples for ACLs and VLAN Maps
Example: Creating an ACL and a VLAN Map to Deny a Packet
This example shows how to create an ACL and a VLAN map to deny a packet. In the first map, any packets
that match the ip1 ACL (TCP packets) would be dropped. You first create the ip1 ACL to permit any TCP
