host ipaddress— Matches packets with a specified IPv4 address
and is an alternative to the IPADRESS/MASK variable for
addresses of end nodes. The HOST keyword indicates that the
IPv4 address is assigned to a specific end node and that no mask
is required.
The VLAN parameter determines if an ACL filters VLANs. You use the
parameter to specify the VID. You can specify one VID per command. If
you omit this parameter, the ACL applies to all traffic. In other words, no
filtering is done by the ACL based on the VLAN.
The following tables provide several examples of the command. In
Table 122, a Numbered IPv4 ACL is created with an ID number of 3097,
that blocks all untagged ingress packets with the specified destination
address of 149.107.22.0/24:
The example in Table 123 creates two Numbered IPv4 ACLs that block all
traffic with specified subnets 149.87.201.0/24 and 149.87.202.0/24.
If you want a port to forward a subset of packets of a more-specific traffic
flow, you have to create a permit ACL for the permitted packets and a
