Source Address, TABLE 29

Page 181 highlights

IP Filter policy 7 Each rule contains the following elements: • Source Address: A source IP address or a group prefix. • Destination Port: The destination port number or name, such as: Telnet, SSH, HTTP, HTTPS. • Protocol: • Action: The protocol type. Supported types are TCP or UDP. The filtering action taken by this rule, either Permit or Deny. For an IPv4 filter policy, the source address has to be a 32-bit IPv4 address in dot decimal notation. The group prefix has to be a CIDR block prefix representation. For example, 208.130.32.0/24 represents a 24-bit IPv4 prefix starting from the most significant bit. The special prefix 0.0.0.0/0 matches any IPv4 address. In addition, the keyword any is supported to represent any IPv4 address. For an IPv6 filter policy, the source address has to be a 128-bit IPv6 address, in a format acceptable in RFC 3513. The group prefix has to be a CIDR block prefix representation. For example, 12AB:0:0:CD30::/64 represents a 64-bit IPv6 prefix starting from the most significant bit. In addition, the keyword any is supported to represent any IPv6 address. For the destination port, a single port number or a port number range can be specified. According to IANA (http://www.iana.org), ports 0 to 1023 are well-known port numbers, ports 1024 to 49151 are registered port numbers, and ports 49152 to 65535 are dynamic or private port numbers. Well-known and registered ports are normally used by servers to accept connections, while dynamic port numbers are used by clients. For an IP Filter policy rule, you can only select port numbers in either the well-known or the registered port number range, between 0 and 49151, inclusive. This means that you have the ability to control how to expose the management services hosted on a switch, but not the ability to affect the management traffic that is initiated from a switch. A valid port number range is represented by a dash, for example 7-30. Alternatively, service names can also be used instead of port number. Table 29 lists the supported service names and their corresponding port number. TABLE 29 Supported services Service name Port number http 443 rpcd 897 securerpcd 898 snmp 161 ssh 22 sunrpc 111 telnet 23 www 80 TCP and UDP protocols are valid selections. Fabric OS v6.1.0and later does not support configuration to filter other protocols. Implicitly, ICMP type 0 and type 8 packets are always allowed to support ICMP echo request and reply on commands like ping and traceroute. For the action, only "permit" and "deny" are valid.

IP Filter policy
7
Each rule contains the following elements:
Source Address:
A source IP address or a group prefix.
Destination Port: The destination port number or name, such as: Telnet, SSH, HTTP, HTTPS.
Protocol:
The protocol type. Supported types are TCP or UDP.
Action:
The filtering action taken by this rule, either Permit or Deny.
For an IPv4 filter policy, the source address has to be a 32-bit IPv4 address in dot decimal notation.
The group prefix has to be a CIDR block prefix representation. For example, 208.130.32.0/24
represents a 24-bit IPv4 prefix starting from the most significant bit. The special prefix 0.0.0.0/0
matches any IPv4 address. In addition, the keyword
any
is supported to represent any IPv4
address.
For an IPv6 filter policy, the source address has to be a 128-bit IPv6 address, in a format
acceptable in RFC 3513. The group prefix has to be a CIDR block prefix representation. For
example, 12AB:0:0:CD30::/64 represents a 64-bit IPv6 prefix starting from the most significant bit.
In addition, the keyword
any
is supported to represent any IPv6 address.
For the destination port, a single port number or a port number range can be specified. According
to IANA (http://www.iana.org), ports 0 to 1023 are well-known port numbers, ports 1024 to 49151
are registered port numbers, and ports 49152 to 65535 are dynamic or private port numbers.
Well-known and registered ports are normally used by servers to accept connections, while
dynamic port numbers are used by clients.
For an IP Filter policy rule, you can only select port numbers in either the well-known or the
registered port number range, between 0 and 49151, inclusive. This means that you have the
ability to control how to expose the management services hosted on a switch, but not the ability to
affect the management traffic that is initiated from a switch. A valid port number range is
represented by a dash, for example 7-30. Alternatively, service names can also be used instead of
port number.
Table 29
lists the supported service names and their corresponding port number.
TCP and UDP protocols are valid selections. Fabric OS v6.1.0and later does not support
configuration to filter other protocols. Implicitly, ICMP type 0 and type 8 packets are always allowed
to support ICMP echo request and reply on commands like ping and traceroute. For the action, only
“permit” and “deny” are valid.
