Usage Guidelines
IPv4 commands are not allowed on a L2 interface. Use the ip access-group command
to attach an access list to an interface. Use the
no ip access-group command to remove
the access list from the interface
Use
mac access-group to attach a MAC access list to an interface
ip address [ <IP Mask>
{secondary}|dhcp]
Sets a static IP address and network mask for a Layer 3
SVI (Switch Virtual Interface)
• <IP/ Mask> {secondary} – Sets the IP address
(10.0.0.1/8)
• secondary – Defines an optional secondary IP
address
• dhcp – Uses a DHCP Client to obtain an IP address for
the interface (this enables DHCP on a Layer 3 SVI)
helper-address <IP>
[<interface>|ge <1-4>|me1|
sa <1-4>|vlan <1-4094>]
Forwards DHCP and BOOTP packets
•<IP> [<interface>|ge|me1|sa|vlan]– Defines the IP to
which DHCP and BOOTP packets are forwarded
• <interface> – Interface name
• ge[<1-4>] – Gigabit Ethernet interface index
• sa[<1-4>] – Static Aggregate interface index
• vlan[<1-4094>] – VID
nat [inside|outside] Sets Network Address Translation (NAT) parameters
•inside – Inside interface
• outside – Outside interface
arp [rate-limit
<1-1000000>|
trust]
Sets arp for the packets
• rate-limit <1-1000000> – Displays the allowed rate in
packets per second
• trust – Displays trust state for arp responses coming in
this interface
dhcp trust Sets dhcp trust state for dhcp responses coming in this
interface
