16  ESR series routers 
6.3.  Device name destination  
The next commands are used to assign device name: 
esr-1000# configure 
esr-1000(config)# hostname <new-name>   
After applying of the configuration, command prompt will be changed to value that is assigned by 
<new-name> parameter. 
6.4.   WAN parameters settings 
You  need  to  assign  device  parameters  determined  by  a  provider  (IP-address,  subnet  mask  and 
gateway address by default) to adjust router network interface in public network (WAN). 
  Command examples of the Static IP-address configuring for subinterface GigabitEthernet 1/0/2.150 
to access the router through VLAN 150.  
Interface parameters: 
  Buffer zone – untrusted 
  IP address – 192.168.16.144; 
  Subnet mask – 255.255.255.0; 
  Gateway IP-address by default – 192.168.16.1. 
esr-1000# configure 
esr-1000(config)# interface gigabitethernet 1/0/2.150 
esr-1000(config-subif)# security-zone untrusted 
esr-1000(config-subif)# ip address 192.168.16.144/24 
esr-1000(config-subif)# exit 
esr-1000(config)# ip route 0.0.0.0/0 192.168.16.1 
Enter the next command after applying of the configuration to check that the address was assigned 
to interface: 
esr-1000# show ip interfaces

Provider can use dynamically assigned addresses in network. DHCP-protocol can be used to get IP-
address if DHCP-server is in network.  
  Adjustment  example  assigned  for  getting  of  the  dynamic  IP-address  from  DHCP-server  on  the 
GigabitEthernet 1/0/4 interface: 
esr-1000# configure 
esr-1000(config)# interface gigabitethernet 1/0/4 
esr-1000(config-if)# ip address dhcp  
esr-1000(config-if)# end 
esr-1000 #commit 
esr-1000 #confirm 
Enter  the  next  command  after  configuration  applying  to  check  that  the  address  was  assigned  to 
interface: 
esr-1000# show ip interfaces
