Ethernet Management Port
The supervisor module provides a standard 10/100/1000 BASET Ethernet management port. When managing a switch, connect the
PC to the Ethernet management port of a Cisco Catalyst 4500E Series switch supervisor engine.
The Ethernet management port can be used (in ROMMON mode only) to recover a switch software image that has been corrupted
or destroyed due to a network catastrophe.
The specific implementation of Ethernet management port depends on the redundancy model you are applying.
The switch cannot route packets from the Ethernet management port to a network port, and from the network port to the Ethernet
port. To obtain these, the Fa1 interface is automatically placed in a separate routing domain (or VRF domain), called mgmtVrf.
(Observe the ip Vrf forwarding mgmtVrf line in the running configuration when you boot.)
Uplink Ports
The supervisor engine has four uplink ports that use small form-factor pluggable (SFP) transceivers or SFP+ transceivers and two
uplink ports that use Quad Small Form-Factor Pluggable Plus (QSFP+) transceivers.
These ports can be used to provide additional port capacity for a fully configured switch or can reduce the need to use a chassis slot
for a module. These ports use hot-swappable optical transceivers.
SFP and SFP+ Ports
Ports are numbered 1 to 4.
These ports can be configured with either SFP transceivers for 1-GE operations or SFP+ transceivers for 10-GE operations. 1 and
10-GE uplink ports operate in full-duplex mode only. Both transceivers use LC-type connectors (optical) or RJ-45 (copper). The SFP
transceivers have LC connectors to interface with multimode fiber (MMF) cable and single-mode fiber (SMF) cable and RJ-45
connectors for the copper interfaces.
Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco
to identify and validate that the SFP module meets the requirements for the device.
QSFP+ Ports
Ports are numbered 1 and 2.
These ports use QSFP+ transceivers for 40-GE operations. QSFP+ transceivers use LC, copper, or MPO-12 connectors.
The 40-GE QSFP+ transceiver module is a hot-swappable, parallel fiber-optical module with four independent optical transmit and
receive channels. These channels terminate in a 40-GE QSFP+ transceiver.
The QSFP+ ports do not support breakout cables.
