• An address learned or configured on one secure interface is seen on
another secure interface in the same VLAN.
When a violation occurs, the port goes into the Restrict mode. In this mode,
packets with unknown source addresses are dropped and you are notified that
a security violation has occurred. An SNMP trap is sent, a syslog message is
logged, and the violation counter increments.
EtherChannels
An EtherChannel (or port group) is a group of two or more Fast Ethernet or
Gigabit Ethernet switch ports bundled into a single logical link, creating a
higher bandwidth link between two switches. The switch supports up to six
EtherChannels. Each EtherChannel can consist of up to eight compatible,
configured ethernet ports.
The following figure shows two EtherChannels. Two full-duplex
10/100/1000-Mbps ports on Switches A and C create an EtherChannel with a
bandwidth of up to 4 Gbps between both switches. Similarly, two full-duplex
10/100 ports on Switches B and D create an EtherChannel with a bandwidth
of up to 400 Mbps between both switches.
If one of the ports in the EtherChannel becomes unavailable, traffic is sent
through the remaining ports within the EtherChannel.
