DRAFT: BROCADE CONFIDENTIAL

protocol The type of IPv6 packet you are filtering. You can specify a well-known name

for some protocols whose number is less than 255. For other protocols, you

must enter the number. Enter “?” instead of a protocol to list the well-known

names recognized by the CLI. IPv6 protocols include:

AHP – Authentication Header

ESP – Encapsulating Security Payload

IPv6 – Internet Protocol version 6

SCTP – Stream Control Transmission Protocol

<ipv6-source-prefix>/<prefix-length

The <ipv6-source-prefix>/<prefix-length> parameter specify a source prefix

and prefix length that a packet must match for the specified action (deny or

permit) to occur. You must specify the <ipv6-source-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.

<ipv6-destination-prefix>/<prefix-l

ength>

The <ipv6-destination-prefix>/<prefix-length> parameter specify a

destination prefix and prefix length that a packet must match for the

specified action (deny or permit) to occur. You must specify the

<ipv6-destination-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

any When specified instead of the <ipv6-source-prefix>/<prefix-length> or

<ipv6-destination-prefix>/<prefix-length> parameters, matches any IPv6

prefix and is equivalent to the IPv6 prefix::/0.

host Allows you specify a host IPv6 address. When you use this parameter, you

do not need to specify the prefix length. A prefix length of all128 is implied.

icmp-type ICMP packets can be filtered by ICMP message type. The type is a number

from 0 to 255.

icmp code ICMP packets, which are filtered by ICMP message type can also be filtered

by the ICMP message code. The code is a number from 0 to 255,

icmp-message ICMP packets are filtered by ICMP messages. See the "Configuring IPv6

ICMP Features" section of the "Configuring IPv6 Connectivity" chapter of the

ServerIron ADX TrafficWorks Switching and Routing Guide.

tcp Indicates the you are filtering TCP packets.

udp Indicates the you are filtering UDP packets.
