IPv6 Support
This chapter includes the following topics:
l IPv6 Notation on page 74
l Enabling IPv6 Support for W-IAP Configuration on page 74
l Firewall Support for IPv6 on page 76
l Debugging Commands on page 76
IPv6 Notation
IPv6 is the latest version of Internet Protocol (IP) that is suitable for large-scale IP networks. IPv6 supports a
128-bit address to allow 2
128
, or approximately 3.4×10
38
addresses while IPv4 supports only 2
32
addresses.
The IP address of the IPv6 host is always represented as eight groups of four hexadecimal digits separated by
colons. For example 2001:0db8:0a0b:12f0:0000:0000:0000:0001. However, the IPv6 notation can be
abbreviated to compress one or more groups of zeroes or to compress leading or trailing zeroes.
The following examples show various representations of the address
2001:0db8:0a0b:12f0:0000:0000:0000:0001
l Valid format—2001:db8:a0b:12f0::0:0:1
l Invalid format—2001:db8:a0b:12f0::::0:1. The “::” sign appears only once in an address.
l With leading zeros omitted—2001:db8:a0b:12f0:0:0:0:1
l Switching from upper to lower case—2001:DB8:A0B:12f0:0:0:0:1
IPv6 uses a "/" notation which describes the number of bits in netmask as in IPv4.
2001:db8::1/128 – Single Host
2001:db8::/64 – Network
IPv6 configuration is supported only on W-IAP214/215, W-IAP224/225, W-IAP274/275, W-IAP314/315, W-
IAP324/325, and W-IAP334/335 access points.
Enabling IPv6 Support for W-IAP Configuration
W-IAPs support IPv6 address mode for the following features:
l Supported IPmodes
l Configuring IPv6 Address for a W-IAP
l RADIUS over IPv6
l SNMP Over IPv6
l SNTP Over IPv6
Supported IPmodes
Instant supports two modes of IP address configuration:
l V4-only—The W-IAP would allow IPv6 clients to pass-through just like the previous Instant release.
l V4-prefer—Supports both IPv4 and IPv6 addresses. If the W-IAP gets both IPv4 and IPv6 responses for a
DNS query, then the W-IAP would prefer the IPv4 DNS address instead of the IPv6 DNS address.
