●
Supervisor engine: These modules work with Supervisor Engine 1A, Supervisor Engine 2,
or Supervisor Engine 720.
●
Slot requirements: These modules can occupy any slot in any Cisco Catalyst 6500
Series chassis.
●
Maximum port density per chassis (48-port modules): These modules support up to
576 ports per Cisco Catalyst 6513, and up to 384 ports per Cisco Catalyst 6509.
●
Maximum port density per chassis (16-port modules): These modules support up to
192 ports per Cisco Catalyst 6513, and up to 128 ports per Cisco Catalyst 6509.
Exclusive features of the Cisco Express Forwarding 256 10/100 and 16-port Cisco Express
Forwarding 256 10/100/1000 Ethernet interface modules follow:
●
Distributed forwarding upgrade: An optional upgrade is available to perform distributed
forwarding; it requires a WS-F6K-DFC3 upgrade to operate with Supervisor Engine 720;
a WS-F6K-DFC upgrade to operate with Supervisor Engine 2 Multilayer Switch Feature
Card 2 (MSFC2); and an SFM.
Exclusive characteristics and features of the 48-port Cisco Express Forwarding 256 10/100/1000
Ethernet interface module follow:
●
Field-installable and -upgradable PoE daughter cards: Sharing the same Category 5
UTP cabling used for network connections, these daughter cards help enable centralized
power distribution to IP phones, wireless access points, and other powered devices.
●
These modules are designed to support field upgrades to the IEEE 802.3af PoE
standard with a new daughter card providing maximum investment protection.
●
TDR: TDR tests cabling by sending signals down the cable to identify faults in each
twisted pair.
●
Distributed forwarding upgrade: This feature is not supported. The WS-X6548-GE-TX,
WS-X6548V-GE-TX, and WS-X6548-GE-45AF do not support distributed forwarding
(WS-F6KDFC and WS-F6K-DFC3A).
