ipf
A screen similar to the following displays:
Displaying all filters:
GP:VL (s/p/vc)
# Type Network Mask Md (Peer ID)
--- -------------- ------------------ ---------------- ------ -----------------------
1 RIP OUT 99.0.0.0 255.0.0.0 A global
2 RIP IN 99.0.0.0 255.0.0.0 B 2:1
3 RIP OUT All Networks B 5:1 (3/1/32)
4 RIP IN All Networks B 6:1 (P1)
This screen contains a list of the existing IP RIP filters. The fields on this screen have the
following meanings:
#
Indicates the index number assigned to identify this filter.
Type
Indicates the type of filter, either RIP Input (
RIP IN) or RIP Output (RIP OUT).
Network
Indicates the IP address that is to be filtered (entered in dotted-decimal format). An entry of
“All Networks” means that all addresses are to be filtered.
Mask
The IP network mask of the network to be filtered (entered in dotted-decimal format). This
field is blank if the network entered is “All Networks.”
Md
Indicates the filter’s mode of operation, either to “allow” traffic (
A) or to “block” traffic (B).
GP:VL (s/p/vc) or (Peer ID)
The first number (
GP) is the Group associated with this entry. The second number (VL) is the
VLAN associated with this entry. When a filter applies to all interfaces, this field will say
“global.” If an entry refers to a Frame Relay interface, column headings for slot, port, and
virtual circuit (s/p/vc) may be displayed when the filter is applied to a particular virtual circuit
rather than to the entire VLAN. If an entry refers to a PPP interface, the Peer ID (Peer ID) may
be displayed when the filter is applied to a particular PPP Peer.
