12 Extreme Networks BlackDiamond 10K-Series Switch Installation Guide
BlackDiamond 10808 Switch Overview
Full-Duplex Support
Extreme Networks switches provide full-duplex support for all ports. This means that frames can be
transmitted and received simultaneously, which, in effect, doubles the bandwidth available on a link.
Most ports on an Extreme Networks switch autonegotiate for half-duplex or full-duplex operation.
Gigabit Ethernet fiber ports and 10 Gigabit Ethernet ports operate in full-duplex mode only in
accordance with technical standards.
Management Ports
The 10/100BASE-TX Ethernet management port allows you to communicate directly to the CPU of the
switch. You can plug an Ethernet cable directly from your laptop into the management port, which
provides you with direct access into the switch. This access allows you to view and locally manage the
switch configurations.
Do not assign an in-band IP address to the management port VLAN. The management port VLAN is an
out-of-band VLAN, so if it is assigned an in-band IP address (an address where the source and
destination are in the same subnet), the switch will treat it as a normal VLAN and attempt to route
traffic through it.
The management port is located on the following Extreme Networks devices:
BlackDiamond—Management Switch Fabric Module (MSM-1 and MSM-1XL)
The MSM-1XL has 256,000 entries in its lookup tables versus 128,000 entries in the MSM-1. The
MSM-1XL is necessary to support BGP-4.
Extreme Networks does not recommend that you use the management port to route traffic to any front
panel port on the switch. The management port is designed for switch management purposes.
Mini-GBIC Type and Hardware/Software Support
The BlackDiamond 10808 switch supports the small form pluggable (SFP) GBIC, also known as the
mini-GBIC. The switches and the modules identify the type of mini-GBIC that is installed and verifies
that the mini-GBIC is an Extreme Networks-certified mini-GBIC.
Mini-GBIC Types and Specifications
The three types of mini-GBIC interfaces are:
SX mini-GBIC, which conforms to the 1000BASE-SX standard
LX mini-GBIC, which conforms to the 1000BASE-LX standard
ZX mini-GBIC, which conforms to the IEEE 802.3z standard
Use only Extreme Networks-certified mini-GBICs, available from Extreme Networks, into the
mini-GBIC port in the switch or module.
