Operation Manual – IP Address and Performance H3C S5500-SI Series Ethernet Switches Chapter 1 IP Address Configuration Figure 1-2 Subnetting a Class B address Note that subnetting is somewhat a tradeoff between subnets and accommodated hosts. For example, a Class B network can accommodate 65,534 hosts before being subnetted. -
Page 5: Assigning An Ip Address To An Interface
The primary and secondary IP addresses you assign to the interface can be located on the same network segment. With S5500-SI series Ethernet switches, you can configure IP addresses for VLAN interfaces and Loopback interfaces. Only 32-bit subnet masks can be configured on Loopback interfaces. - Page 6 Operation Manual – IP Address and Performance H3C S5500-SI Series Ethernet Switches Chapter 1 IP Address Configuration II. Network diagram Figure 1-3 Network diagram for IP address configuration III. Configuration procedure If only one IP address is configured on Vlan-interface1 of the switch, only part of the hosts can be accessed from external network through the switch.
