Note 1: DHCP servers usually have the ability to assign a default route to
DHCP clients. Make sure that the DHCP server assigns only one
default route, even you are using many different IP interfaces on the
same BelAir platform (for example, a management IP interface and a
VLAN IP interface).
Note 2: You must configure the DHCP server lease time to be one minute or
longer.
Note 3: If the network contains nodes with static IP addressing and nodes with
dynamic IP addressing, make sure the DHCP server does not issue
addresses that been previously issued statically.
Renewing the IP
Address
/protocol/ip/renew ip {system | vlan <1-2814>}
This command is used when the node is configured to dynamically receive IP
addresses. See
“Configuring Dynamic IP Addressing” on page 44
Issuing this command causes the DHCP server to renew the IP address of the
node’s management interface or of the VLAN.
CAUTION!
Using this command may cause the DHCP server to change the IP address of
the node’s management interface. If this happens you may need to reconnect to
the node using the new IP address.
Auto-IP
/protocol/ip/set auto-IP {enabled | disabled}
This command automatically configures the node to have a specific default IP
address if it cannot get an IP address from the DHCP server or when it is in
factory default mode. The default IP address is
169.254.1.x
with a mask of
255.255.255.0
; where
x
is the last byte of the node’s MAC address. This allows
you to still access the node if the DHCP server should fail. The default setting is
enabled
.
Setting a Static IP
Address and Subnet
Mask
/protocol/ip/set interface {system | vlan <1-2814>}
static <ip addr> <mask>
[delay-activation]
/protocol/ip/del ip vlan <1-2814>
The
set interface
command specifies that the node uses static IP addressing for
the node’s management interface as well as any VLANs it may have. If you
specify a new VLAN, then that VLAN is created. The
del ip vlan
command
deletes VLAN IP parameters previously created with the
set interface
command.
