PowerConnect 6224/6224F/6224P/6248/6248P Release Notes
¾Configured Tunnels MTU
To comply with RFC 4213, Basic Transition Mechanisms for IPv6 Hosts and Routers, the IPv6 MTU on configured IPv6 over IPv4 tunnels was changed from 1480 bytes to 1280 bytes.
¾IPv6 6 to 4 Auto Tunnels
The 6 to 4 tunnels automatically formed IPv4 6 to 4 tunnels for carrying IPv6 traffic. The automatic tunnel IPv4 destination address is derived from the 6 to 4 IPv6 address of the tunnel next hop. There is support for a 6 to 4 border router that connects a 6 to 4 site to a 6 to 4 domain. It sends/receives tunneled traffic from routers in a 6 to 4 domain that includes other 6 to 4 border routers and 6 to 4 relay routers.
¾VRRP Route Interface Tracking
This extends the capability of the Virtual Router Redundancy Protocol (VRRP) to allow tracking of specific route/interface IP state within the router that can alter the priority level of a virtual router for a VRRP group.
The exception to this is, if that VRRP group is the IP address owner, its priority is fixed at 255 and can not be reduced through tracking process.
¾ICMP Throttling
This adds configuration options for the transmission of various types of ICMP messages. This project adds the following configuration options:
•Rate limiting the generation of ICMP error messages.
•Suppression of ICMP echo replies.
•Suppression of ICMP Redirects.
•Suppression of Destination Unreachables.
¾IP Helper
Provides the ability to enable DHCP relay on specific interfaces, with DHCP server addresses specified independently on each interface. The ip
¾OSPF Enhancements
A CLI command is added with options to do the following:
•Disable and
•Clear the OSPF configuration
•Bounce all or specific OSPF neighbors
•Flush and
•Clear OSPF statistics
¾Support of IPv6 routes in
Support for IPv6 routes has been added to
