Cisco CATALYST 1924 ENTERPRISE SWITCH Specification Guide
Overview 1-5
Fast EtherChannel
Fast EtherChannel
Fast EtherChannel links provide parallel bandwidth of up to 400 Mbps (in full duplex
mode) between a Catalyst 2820 series or Catalyst 1900 series switch and another switch or
host by grouping two Fast Ethernet interfaces into a single logical transmission path.

VLAN Trunk Protocol
Allows VLAN naming consistency and connectivity
between all devices in a management domain. When
new VLANs are added to a Catalyst 2820 or
Catalyst 1900 switch in a management domain, the
VLAN Trunk Protocol (VTP) automatically distributes
the information to all the devices in the management
domain. VTP advertisements are transmitted on all
trunk connections, including ISL, IEEE 802.10, and
ATM LANE.

VTP Pruning
Enhances network bandwidth use by reducing
unnecessary flooded traffic, including broadcast,
multicast, and flooded unicast packets. This feature
restricts flooded traffic to only those trunk links that the
traffic must use to access the appropriate network
devices.

Static Port VLAN
Membership
Membership
Manually assigns a port to a VLAN. You need to
reconfigure the switch to change the VLAN assignment
to a static port.

Dynamic Port VLAN
Membership
Membership
Provides the flexibility to move a connection from a port
on one switch to a port on another device in the network
while retaining the VLAN identity of the host. You can
assign dynamic ports to a VLAN based on the source
MAC address of the hosts connected to that port.

Dynamic Inter-Switch
Link (DISL) Protocol
Link (DISL) Protocol
Synchronizes the configuration of two interconnected
Fast Ethernet interfaces to ensure that both interfaces are
either in trunking or nontrunking mode.
