Monitoring Network Connections
Table 25-1 describes the tasks and commands used to monitor network connections at the switch
level.
Refer to the CLI Reference for your platform for more information about the commands listed
below.
IPv6 Routing Configuration
IPv6 routing must be enabled with a license key. If you have purchased an advanced or IPv6
routing license key, and have enabled routing on the device, you must activate your license as
described in the chapter entitled “Activating Licensed Features” in order to enable the IPv6
routing configuration command set. If you wish to purchase an advanced IPv6 routing license,
contact Enterasys Networks Sales.
Overview
IPv6 and IPv4 coexist on the Enterasys Fixed Switch platforms. As with IPv4, IPv6 routing can be
enabled on VLAN interfaces. Each Layer 3 routing interface can be used for IPv4, IPv6, or both.
The Enterasys Fixed Switches support all IPv6 address formats, including global unicast
addresses, link-local unicast, global multicast, scoped multicast (including local scoped multicast),
IPv4 compatible addresses, unspecified addresses, loopback addresses, and anycast addresses.
Refer to the following RFCs for more information about IPv6 address formats:
• RFC 4291, “IP Version 6 Addressing Architecture”
• RFC 3587, “IPv6 Global Unicast Address Format”
• RFC 4007, “IPv6 Scoped Address Architecture”
The basic IPv6 protocol specifies PDU options of two classes, both of which are supported: hop-
by-hop options and destination options. While new options can be defined in the future, the
following are currently supported: routing (for source routing), fragment, router alert, and pad.
Jumbograms are not supported. In IPv6, only source nodes fragment. Path MTU discovery is
therefore a requirement. Flow labels are ignored.

Task Command(s)
Display IPv6 network connection information show ipv6 netstat
Display the system IPv6 Neighbor Discovery cache show ipv6 neighbors
Test network connectivity by sending IP ping
requests
ping ipv6 {ipv6-addr | interface host
link-local-addr}[size num]
Discover the routes that packets actually take when
traveling to their destination through the network on
a hop-by-hop basis
traceroute ipv6 ipv6-addr
