port of the remote configuration host and that of the switch are
not in the same network segment, it is also necessary to
configure the static route.
Static route is a simple unicast route protocol. The next-hop
address to a destination network segment is specified by user,
where next hop is also called bridge. Static route involves
destination address, destination address mask, next-hop
address, and egress interface. Destination address and
destination address mask describe the destination network
information. The next-hop address and egress interface
describe the way that switch forwards destination packet.
ZXR10 2920/2928/2952 allows addition and deletion of entries
in the static ARP table. ARP table records mapping between IP
address of each node in same network and MAC address.
When sending IP packets, switch first checks whether
destination IP address is in the same network segment. If yes,
switch checks whether there is a peer end IP address and MAC
address mapping entry in ARP table.
îš„ If yes, switch directly sends the IP packets to this MAC
address.
îš„ If MAC address corresponding to peer end IP address cannot
be found in ARP table, an ARP Request broadcast packet is
sent to the network to query peer end MAC address.
Generally, entries of the ARP table on the switch are dynamic.
Static ARP table entry is configured only when the connected
host cannot respond to the ARP Request.
To configure the layer 3 function, use command config router
to enter into layer 3 configuration mode first.
Configuring IP Port
This topic describes the configuration of IP port on ZXR10
2920/2928/2952.
For the configuration of IP port, perform the following steps.
1. To set IP address and mask address of layer 3 port, use
command set ipport <0-63> ipaddress {<A. B. C.
D/M>|<A. B. C. D> < A. B. C. D>} in router config
mode. This is shown in
Table 243.
