Chapter 1 Product Overview
Management Features
FAT32 FAT32 filesystem type
ext2 ext2 filesystem type
For SD card under IOS XE 3.1.0SG, the default format is FAT16:
Switch# format slaveusb0: ?
FAT16 FAT16 filesystem type
FAT32 FAT32 filesystem type
ext2 ext2 filesystem type
FAT File Management System on Supervisor Engine 6-E, Supervisor Engine
6L-E, Catalyst 4948E, Catalyst 4948E-F, and Catalyst 4900M
The FAT file system is widely used to manage files on devices disks and flash. The support of the FAT
file system allows you to easily remove, add, and/or transfer images to and from the flash.
Forced 10/100 Autonegotiation
This feature allows you to configure a port to limit the speed at which it will autonegotiate to a speed
lower than the physically maximum speed. This method of reducing the throughput incurs much less
overhead than using an ACL.
Intelligent Power Management
Working with powered devices (PDs) from Cisco, this feature uses power negotiation to refine the power
consumption of an 802.3af-compliant PD beyond the granularity of power consumption provided by the
802.3af class. Power negotiation also enables the backward compatibility of newer PDs with older
modules that do not support either 802.3af or high-power levels as required by IEEE standard.
For more information on Intelligent Power Management, see the “Intelligent Power Management”
section in
Chapter 15, “Configuring Power over Ethernet.”
MAC Address Notification
MAC address notification monitors the MAC addresses that are learned by, aged out, or removed from
the Catalyst 4500 series switch. Notifications are sent out or retrieved by using the
CISCO-MAC-NOTIFICATION MIB. It is typically used by a central network management application
to collect such MAC address notification events for host moves. User-configurable MAC table utilization
thresholds can be defined to notify any potential DoS or man-in-the-middle attack.
For information on MAC Address Notification, see Chapter 4, “Administering the Switch.”
MAC Notify MIB
The MAC Notify MIB feature monitors network performance, utilization, and security conditions
enabling a network administrator to track the MAC addresses that are learned or removed on the switch
forwarding the Ethernet frames.
