Field Description
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.
Clearing global IPv6 information
You can clear the following global IPv6 information:
• Entries from the IPv6 cache.
• Entries from the IPv6 neighbor table.
• IPv6 routes from the IPv6 route table.
• IPv6 traffic statistics.
Clearing the IPv6 cache
You can remove all entries from the IPv6 cache or specify an entry based on the following:
• IPv6 prefix.
• IPv6 address.
• Interface type.
For example, to remove entries for IPv6 address 2000:e0ff::1, enter the following command at the Privileged EXEC level or any of the
Config levels of the CLI.
device#clear ipv6 cache 2000:e0ff::1
Syntax: clear ipv6 cache [ ipv6-prefix / prefix-length | ipv6-address | ethernet port | tunnel number | ve number | vrf vrf-name ]
You must specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373. You must
specify the prefix-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prefix parameter and precede the prefix-
length parameter.
You must specify the ipv6-address parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.
The ethernet | tunnel | ve | vrf parameter specifies the interfaces for which you can remove cache entries. If you specify an Ethernet
interface, also specify the port number associated with the interface. If you specify a VE, VRF, or tunnel interface, also specify the VE,
VRF name, or tunnel number, respectively.
Clearing IPv6 neighbor information
You can remove all entries from the IPv6 neighbor table or specify an entry based on the following:
• IPv6 prefix
