VOS7 New Features and Software Updates Files

This release is exactly equivalent to VOS 07_06_01 and includes all of those new features, but also includes more specialist cryptographic features.

Multi Level User Accounts:

• Restrict access to certain features via a Users menu
• New login and logout scheme
• Limit the number of consecutive failed login attempts from any user
• Select customised welcome banner text
• Addition of an SNMP trap to detect 'Login Blocked'
• Addition of an alarm condition 'Account Blocked'

IPSec & IKE is available under the control of an IPSec & IKE Feature Key. IPSec has been implemented to allow encryption and/or authentication of two different types of traffic in the Vocality multiplexer and router software architecture. Security Associations (SAs) can be configured to provide an IPSec path to a peer device.

SSH Server has been added to allow secure access to the supervisor port. Once connected the interface provided is identical to the menu, TTY and diagnostics shell interface provided via the supervisor port or Telnet. The SSH Feature Key needs to be enabled, access must be permitted via the access table, and a host key will have to be generated for SSH connections to succeed.

DHCP enhancements:

• Multiple instance support – to allow separate instances of the DHCP server to run independently on separate LANs and/or VLANs.
• Generic option support – to allow support for any standard (non-vendorspecific) DHCP option.

NAT to allow address translation between private and public networks. Once configured, operation is dynamic – translated sessions are learnt from protocol sessions initiated on the private networks.

Ethernet Traffic Shaping provides mechanisms for the management of outgoing traffic on Ethernet ports. It allows a limit to be applied to the bandwidth transmitted to an Ethernet port. This is intended for cases where there is a bandwidth-limited device such as a satellite modem beyond the immediate Ethernet segment. Within this bandwidth, different priorities can be applied to traffic using simple Precedence or Weighted Fair Queuing (WFQ) algorithms.

ISDN CLI and Cause Code Transparency allows the carriage of ISDN Calling Party Number and Cause Code information transparently between PRI ISDN connections.

Border Gateway Protocol (BGP) protocol support has been added to the embedded IP router. The Border Gateway Protocol (BGP) is an exterior, or interdomain, routing protocol. BGP is used to exchange routing information between multiple transit autonomous systems, between transit and stub autonomous systems, or between multiple stub autonomous systems.

IP TOS / DSCP Manipulation which introduces the ability to override the DCSP field of IP packets in an intelligent manner
