Sessions
Destination Address /
Mask
Destination address of the packets. • For IP, IPIP4, GRE.IP, or GTP.IPv4 addresses, enter a valid
IPv4 address in dotted-quad format n.n.n.n, where n is 0 to
255. The default (if blank) is 255.255.255.255.
• For IPv6 or GTP.IPv6 addresses, enter a valid IPv6 address in
any allowed IPv6 address format. For example:
–
1080::8:800:200C:417A
Note See RFC 2373 for valid text representations.
For MAC address, enter hh hh hh hh hh hh, where hh is a
hexadecimal number from 0 to 9 or a to f. The default is
ff ff ff ff ff ff.
The mask applied to the destination
address.
• If a bit in the Dest. Mask is set
to 1, the corresponding bit in
the address is relevant.
• If a bit in the Dest. Mask is set
to 0, the corresponding bit in
the address is ignored.
• For IP, IPIP4, GRE.IP, or GTP.IPv4 addresses, enter a valid
IPv4 address in dotted-quad format n.n.n.n, where n is 0 to
255. The default (if blank) is 255.255.255.255.
• For IPv6 or GTP.IPv6 addresses, enter a valid IPv6 address in
any allowed IPv6 address format. The default mask (if blank)
for IPv6 addr esses is ffff:ffff:ffff: ffff:ffff:ffff:ffff:ffff
Note See RFC 2373 for valid text representations.
For MAC address, enter hh hh hh hh hh hh, where hh is a
hexadecimal number from 0 to 9 or a to f. The default is
ff ff ff ff ff ff.
Network
Encapsulation
The protocol to match with the
packet.
Choose the protocol from the drop-down list.
• Choose MAC to use the source/ destination MAC address of
the packets.
• Choose IP to use the source/destination IP addresses of the
packets.
• Choose IPIP4 for IP addresses including those tunneled over
IP protocol 4.
• Choose GRE.IP for IP addresses including those tunneled
over GRE.
• Choose IPv6 for addresses using IP version 6.
• Choose GTP.IPv4 for IPv4 address for tunneled packet over
GTP.
• Choose GTP.IPv6 for IPV6 address for tunneled packet over
GTP.
Both Directions
(check box)
This check box indicates whether
the filter is applied to traffic in both
directions.
If the source is host A and the destination is host B, enabling both
directions filters packets from A to B and B to A.
If the source is host A and the destination is not specified,
enabling both directions filters packets both to and from host A.
The “both directions” check box also affects the ports and not
only the addresses (the same logic applies).
