Configuring Security

Configuring Port Security

Cisco Small Business 200 1.1 Series Smart Switch Administration Guide 243

• Storm Control Rate Threshold—Enter the maximum rate at which unknown

packets can be forwarded. The default for this threshold is 10,000 for FE

devices and 100,000 for GE devices.

• Storm Control Mode—Select one of the modes:

- Unknown Unicast, Multicast & Broadcast—Counts unknown Unicast,

Broadcast, and Multicast traffic towards the bandwidth threshold.

- Multicast & Broadcast—Counts Broadcast and Multicast traffic towards

the bandwidth threshold.

- Broadcast Only—Counts only Broadcast traffic towards the bandwidth

threshold.

STEP 4 Click Apply. Storm control is modified, and the Running Configuration file is

updated.

Configuring Port Security

Network security can be increased by limiting access on a port to users with

specific MAC addresses. The MAC addresses can be either dynamically learned

or statically configured.

Port security monitors received and learned packets. Access to locked ports is

limited to users with specific MAC addresses.

Port Security has two modes:

• Classic Lock—All learned MAC addresses on the port are locked, and the

port does not learn any new MAC addresses. The learned addresses are not

subject to aging or re-learning.

• Limited Dynamic Lock—The switch learns MAC addresses up to the

configured limit of allowed addresses. After the limit is reached, the switch

does not learn additional addresses. In this mode, the addresses are

subject to aging and re-learning.
