ability to use IPFlow. The transition should be transparent to the SP/customer and
keep all of the current features.
3460 E1 Trunking Gateway
In the 3460, for E1 Interfaces only, allow consecutive DS0 switching configuration.
This configuration can consist of TDM Voice and Data traffic, from one E1 Interface
to the other E1 interface. These consecutive DS0's must start at DS0 number 1.
Remaining DS0's are allowed to carry channelized data. This feature will be
enabled on the 3460 and be included in the IP+, SNA+, and Multi-Service license.
The feature is not be implemented in the T1 Daughter Card for the 3460.
DHCP Server extended number of clients from 128 to 255 and introduce
exception rules
Current DHCP implementation is limited to 16 subnets and 128 clients per subnet,
for a maximum of 2,048 clients. Some large customers need more than 2,048 clients,
and need to organize their IP addressing into more than 16 subnets. One customer,
e.g., has hundreds of institutions: Government departments, schools, hospitals,
police, etc., each one of which has hundreds of IP addresses. For example:
0.1.1.0 to 10.1.1.254 - Department of health
10.1.2.0 to 10.1.2.100 - Police
10.1.2.101 to 10.1.2.254 - Secretary of transports
10.1.3.0 to 10.1.3.90 - School A
10.1.3.91 to 10.1.3.127 - School B
In addition, there are blocks of IP addresses that must be excluded.
In this release, to accommodate the needs of such customers, the following changes
are being made:
* The number of clients per /24 subnet (mask 255.255.255.0) is being increased to
254. This does not require a configuration change.
