IP Addressing 185
Dynamic Assignment
Dynamic assignment of an IPv4 address can be configured in the IPv4
Interface
page.
It can also be performed using CMC management by requesting dynamic
assignment of an IP address from the CMC management.
NOTE: When a static address is removed from the OOB port, the DHCP client is
enabled on this port. The user cannot delete IP DHCP configuration from the OOB
port without defining a new static address.
Static Assignment
The static IPv4 address on an IP interface can be assigned in the IPv4
Interface page.
Number of In-Band IP Addresses
Only a single IP address can be assigned on the OOB port.
The number of IP addresses that can be assigned on in-band ports vary
according to the system mode:
• In Layer 2 mode in R1-2401, a single IP address can be assigned, either
statically or by a DHCP server.
• In Layer 2 + Static Routing mode on R1-2401 devices and (always) on R1-
2210 devices, multiple IP addresses can be assigned, either statically or by a
DHCP server.
NOTE: The IPv4 address assigned to the OOB interface is not accessible through
in-band interfaces and vice-versa.
IPv4 Default Gateway
A default gateway can be assigned on any IPv4 interface in the system (OOB,
Port, LAG or VLAN).
The IPv4 default gateway can be assigned statically or received by a DHCP
server according to the configuration in the IPv4 Interface page. When you
enable DHCP dynamic assignment of IP addresses, the default gateway is also
received from the DHCP server. DHCP assignment is the default.
An IPv4 default gateway can be defined on an OOB interface (either assigned
statically or by a DHCP server) and also on in-band ports.
