The Cisco Catalyst Operating System Software Version 7.2(2) for the Cisco Catalyst 6500 Series Switches also
includes support for the Cisco 7606 Internet Router (Table 2):
Note: The Cisco 7606 Internet Router supports all supervisor engine configurations.
Software Features
Software features of the Cisco Catalyst Operating SystemSoftwareVersion 7.2(2) supported on CiscoCatalyst6500
Series switches and Cisco 7600 Internet Routers are given in Table 3.

Software Feature Description
Bridged NetFlow statistics This feature enables you to explicitly enable/disable bridged flow statistics
on a per-VLAN
1
basis when the flows are exported as part of NetFlow data
export, or NDE. This bridged flow statistics information will appear in the
output of the show mls nde command.
Broadcast suppression
enhancement
Broadcast suppression limits the amount of bandwidth allowed for
broadcast frames. It measures how much broadcast traffic is occurring,
and compares it to a user configurable threshold over a user configurable
interval. If theamount of broadcasttrafficreaches the thresholdduring this
interval, the user can choose to have the switch either drop the broadcast
frames or (in Version 7.2.2 and later) shutdown a port.
This feature is useful particularly when it is enabled on all except one of
the ports that contribute to a spanning-tree loop. For example, if an errant
condition causes an increasing level of broadcasts within a loop, the
feature triggers the port shutdown and breaks the loop.
Extended trust for Cisco Discovery
Protocol devices
The trusted boundary feature uses the Cisco Discovery Protocol to detect
the presence of an IP phone on a given port, thus eliminating the potential
security problem that arises when PCs are able to tag their own packets. If
the switch detects the phone removal, the switch port is automatically set
to “untrusted” so the users cannot disconnect the phone from the network
and directly plug their PCs into the switch port to take advantage of the
trust-cos
2
setting on the switch.
Jumbo frames on sc0 This feature enables the Cisco Catalyst 6500 Series Switch to support
jumbo frames on the management interface, sc0.
Layer 2 Protocol Tunneling The L2 Protocol Tunneling feature allows the tunneling of control protocol
PDUs
3
, such as STP
4
, Cisco Discovery Protocol and VTP
5
, which was not
achieved by the existing feature of .1q-in-.1q tunneling on the Cisco
Catalyst 6500 platform.
