2-port Fast Ethernet for ISL Applications

2-port Fast Ethernet for ISL Applications

The 2-port Fast Ethernet/ISL fiber and copper port adapters provide convenient 100BaseT Fast Ethernet connectivity for Inter-Switch Link (ISL) VLAN transport over switch-to-switch backbone connections or switch-to-server data center attachments. The inter-VLAN bridging and routing functionality of the PA-2FEISL allows network administrators to deploy 100 Mbps Token Ring VLAN transport, 100 Mbps Ethernet VLAN transport, and bridging or routing between the mixed LAN types using the same physical ISL trunk links. This flexibility enables network administrators to build high-speed, frame-based network topologies, and architect a smooth migration path from Token Ring to cost-effective 100 Mbps or Gigabit Ethernet backbone environments.

There are two models of the Fast Ethernet/ISL 100BaseT port adapters to support connections to Category 5 UTP cable for 100BaseTX (RJ-45) applications and to fiber for 100BaseFX (SC-type fiber-optic connector) applications.


Note The two-port Fast Ethernet/ISL port adapters are designed to provide inter-VLAN bridging and routing for Token Ring users. Native Fast Ethernet users should use the single-port Fast Ethernet PA-FE-TX or PA-FE-FX adapters for higher performance.
