Information About IPv4
You can configure IP on the switch to assign IP addresses to network interfaces. When you assign IP
addresses, you enable the interfaces and allow communication with the hosts on those interfaces.
You can configure an IP address as primary or secondary on a switch. An interface can have one primary
IP address and multiple secondary addresses. All networking switches on an interface should share the
same primary IP address because the packets that are generated by the switch always use the primary
IPv4 address. Each IPv4 packet is based on the information from a source or destination IP address. See
the
You can use a subnet to mask the IP addresses. A mask is used to determine what subnet an IP address
belongs to. An IP address contains the network address and the host address. A mask identifies the bits
that denote the network number in an IP address. When you use the mask to subnet a network, the mask
is then referred to as a subnet mask. Subnet masks are 32-bit values that allow the recipient of IP packets
to distinguish the network ID portion of the IP address from the host ID portion of the IP address.
