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).
