Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 209)

Field Description
passive opens The number of TCP connections opened by the router in response to connection
requests (TCP SYNs) received from other devices.
failed attempts This information is used by Brocade Technical Support.
active resets The number of TCP connections the router reset by sending a TCP RESET message to
the device at the other end of the connection.
passive resets The number of TCP connections the router reset because the device at the other end of
the connection sent a TCP RESET message.
input errors This information is used by Brocade Technical Support.
in segments The number of TCP segments received by the router.
out segments The number of TCP segments sent by the router.
retransmission The number of segments that the router retransmitted because the retransmission timer
for the segment had expired before the device at the other end of the connection had
acknowledged receipt of the segment.
DHCP relay agent for IPv6
A client locates a DHCP server using a reserved, link-scoped multicast address. Direct communication
between the client and server requires that they are attached by the same link. In some situations
where ease-of-management, economy, and scalability are concerns, you can allow a DHCPv6 client to
send a message to a DHCP server using a DHCPv6 relay agent.
A DHCPv6 relay agent, which may reside on the client link, but is transparent to the client, relays
messages between the client and the server. Multiple DHCPv6 relay agents can exist between the
client and server. DHCPv6 relay agents can also receive relay-forward messages from other relay
agents; these messages are forwarded to the DHCP server specified as the destination.
When the relay agent receives a message, it creates a new relay-forward message, inserts the original
DHCPv6 message, and sends the relay-forward message as the DHCP server.
Configuring DHCP for IPv6 relay agent
To enable the DHCPv6 relay agent function and specify the relay destination (the DHCP server)
address on an interface, enter the following command at the interface level:
device(config)# interface ethernet 2/3
device(config-if-e10000-2/3)#ipv6 dhcp-relay destination 2001::2
deviceconfig-if-e10000-2/3)#ipv6 dhcp-relay destination fe80::224:38ff:febb:e3c0
outgoing-interface ethernet 2/5
Syntax: [no] ipv6 dhcp-relay destination ipv6-address [ outgoing-interface interface-type port-
num ]
