New features for this release

New features for this release include:

•

"Bandwidth Management" (page 8)

•

"Certiﬁcate Management" (page 9)

•

"IPSec Tunnel Nail Up" (page 9)

•

"SSH/HTTPS for Remote Management" (page 9)

Bandwidth Management

With the Bandwidth Management feature, you can allocate the outgoing capacity of an interface to speciﬁc types of trafﬁc. You can also ensure that the Contivity 251 forwards certain types of trafﬁc (especially real-time applications) with minimum delay. This feature allows you to manage bandwidth for the Contivity 251 by conﬁguring classes and ﬁlters for LANs and WANs.

Release 2.3 March 2006

Contivity 251 conﬁguration tasks 9

Certiﬁcate Management

The Contivity 251 uses certiﬁcates (also called digital IDs) to authenticate users. Certiﬁcates are based on public-private key pairs. Certiﬁcates provide a way to exchange public keys for use in authentication.

IPSec Tunnel Nail Up

This feature ensures that the Contivity 251 automatically renegotiates an IPSec tunnel when the IPSec Security Association (SA) lifetime expires. When the Contivity 251 restarts, it automatically renegotiates any nailed-up tunnels. In effect, the IPSec tunnel becomes an always on connection after the tunnel is initiated.

SSH/HTTPS for Remote Management

Secure Shell (SSH) is a secure communication protocol that combines authentication and data encryption to provide secure encrypted communication between two hosts over an unsecured network. Hypertext Transfer Protocol over SSL (HTTPS) is a web protocol that encrypts and decrypts web pages. The Contivity 251 device supports these protocols for remote management purposes.

Contivity 251 user notes

In certain cases, an object may be colored red to indicate that it is a duplicate even after the duplicated line is deleted. Because the line is in red, it is not exported to the device. To correct this situation so that the line can be exported, modify the duplicate object, select another object to remove the red, and then change the object back to the desired value.

The order of the SUA/NAT address mapping rules in the Contivity 251 device is important because they are processed in numeric order. Both CCM and Contivity 251 provide for gaps in the rules speciﬁcations, so that you can insert rules between other rules in the table. CCM expands on this capability by providing the ability to Copy a rule from one place in the table and Paste it to overwrite another rule in the table. Note that, when using this CCM capability, you need to write over other existing rules in the table; hence, leaving gaps within the table makes rearranging rules easier. (Q00857737)

Note: Do not enter special characters, such as ", into any text ﬁelds in CCM. CCM does not accept special characters in text ﬁelds.

Contivity 251 conﬁguration tasks

The CCM client must be connected to the CCM server to perform the conﬁguration tasks described in this guide. To perform conﬁguration operations on the Contivity devices in the network, the CCM server requires TCP/IP connectivity to the Contivity 251 device. Any other sessions to the Contivity 251 device should be logged out before attempting to access the Contivity 251 device with CCM.
