NAC Controller PEP Network Requirements

Link Aggregation

Link Aggregation is a method of grouping multiple physical ports on a network device into one logical link according to the IEEE 802.3ad‐2002 standard. Because Link Aggregation is standards based, it allows for automatic configuration with manual overrides (if applicable), and can operate on 10 Mbps, 100 Mbps, or 1000 Mbps Ethernet full duplex ports. Thus the network administrator can combine a group of five 100 Mbps ports into a logical link (trunk) that functions as a single 500 Mbps port. As long as the NAC Controller PEPs agree on which ports are in the trunk, there are no problems with looping, and the Spanning Tree can treat this trunk as a single port.

In normal usage (and typical implementations) there is no need to enable/disable ports for Link Aggregation. The default values will result in the maximum number of aggregations possible. If the switch is placed in a configuration with its peers not running the protocol, no aggregations will be formed and the NAC Controller PEPs will function normally (that is, Spanning Tree will block redundant paths).

For details about the commands involved with configuring the Link Aggregation function, refer to the Enterasys Matrix DFE‐Diamond/Platinum Series Configuration Guide.

10BASE-T Network

When connecting a 10BASE‐T segment to any of the fixed front panel ports of the 2S4082‐25, ensure that the network meets the Ethernet network requirements of the IEEE 802.3‐2002 standard for 10BASE‐T. Refer to the Cabling Guide for details.

Note: If a port is to operate at 100 Mbps, Category 5 cabling must be used. Category 3 cabling does not meet 100 Mbps specifications. For 10 Mbps operation only, Category 3 or Category 5 cabling can be used. Refer to “100BASE-TX Network” on page 2-4 for information about 100BASE-TX networks and cabling.

100BASE-TX Network

The fixed front panel ports of the 2S4082‐25 provide a connection that supports Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 100BASE‐TX Fast Ethernet network requirements for the devices to operate at 100 Mbps. Refer to the Cabling Guide for details.

Note: The fixed ports of the NAC Controller PEP support Category 5 UTP cabling with an impedance between 85 and 111 ohms for 100 Mbps operation. The NAC Controller PEP is capable of operating at 10, 100, or 1000 Mbps and can automatically sense the port speed of the other device and adjust its speed accordingly.

1000BASE-T Network

The 2S4082‐25 supports 10/100/1000 Mbps by means of fixed RJ45 front panel connectors. These connections support copper wire connections that can operate up to 1000 Mbps. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 network requirements for the devices to operate at Gigabit speed.

Note: The fixed ports of each NAC Controller PEP support Category 5 UTP cabling with an impedance between 85 and 111 ohms for 100 and 1000 Mbps operation and can automatically sense the port speed of the other device and adjusts its speed accordingly.
