Management Port

The management port is a 10/100/1000 copper Ethernet port directly connected to the route processor. With
an network interface card (NIC) interface, it supports TFTP image downloading, network management, SNMP,
Telnet, and SSH connections. The management port is isolated from other ports in the system; it is not part
of the EARL forwarding logic. The management port provides direct access to the CPU, even when the system
is heavily loaded.
The management port is a Layer 3 port in host mode, and only accepts traffic that terminates on the router.
This port does not route packets between itself and other ports. The port processes only the following packet
types and properly enqueues them:
• Address Resolution Protocol (ARP)
• IPv4 unicast
• IPv6 unicast
• Cisco Discovery Protocol (CDP)
• Link Layer Discovery Protocol (LLDP)

USB Port Type B

The USB 2.0 port Type B serves as a second console connection to the route processor. The USB console
port connection uses a USB Type A to Type B cable. The USB console interface speeds are the same as the
RJ-45 console interface speeds. Windows PCs need a driver for the USB port.
The USB-prefer mode is the default, but it can be overridden using the command-line interface (CLI). When
this port is in USB-prefer mode, the RJ-45 console port will be disabled if both ports are connected. For more
information on using the CLI to configure the USB console interface, see the Catalyst 6500 software guide.

USB Type A Port

The USB Type A port is the only external storage interface for this switch. The port is connected to the route
processor, which allows the Cisco IOS software to access the port. The port supports Cisco USB flash drives
with capacities from 128 MB to 8 GB (USB devices with port densities of 128 MB, 256 MB, 1 GB, 4 GB,
and 8 GB are supported). Cisco IOS software provides standard file system access to the flash device: read,
write, erase, and copy. The software also provides the ability to format the flash device with a FAT file system
(FAT32 and FAT16).
