Extreme Network Extreme Switch - How to configure DHCP Server in EXOS https://www.analysisman.com/2020/09/extreme-exos-dhcp-server.html Step 1. Create and configure a VLAN with IP address and Ports create vlan   vlan_name   configure vlan   vlan_name   ipaddress   address/mask exos-switch#  create vlan DHCP_Server exos-switch#  configure vlan DHCP_Server ipaddress 192.168.100.1/24 IP interface for VLAN DHCP_Server has been created. exos-switch#  configure vlan DHCP_Server add ports 1-10  Port 1 2 3 4 5 6 7 8 9 10 untagged has been auto-moved from VLAN "Default" to "DHCP_Server". Step 2. Enable DHCP client ports with the VLAN   enable dhcp ports   port_list   vlan   vlan_name exos-switch#  enable dhcp ports 1-10 vlan DHCP_Server Step 3. Configure DHCP address range with the VLAN   configure vlan   vlan_name   dhcp-address-range   start_addr   -   end_addr exos-switch#  configure vlan DHCP_Server dhcp-address-range 192.168.100.10 - 192.168.100.200 Step 4. Configure DHCP options with the VLAN     configure vlan  vlan_name  dhcp-options default-gateway  gateway_addr     configure vlan  vlan_name  dhcp-options dns-server  dns_addr exos-switch#  configure vlan DHCP_Server dhcp-options default-gateway 192.168.100.1 exos-switch#  configure vlan DHCP_Server dhcp-options dns-server primary 1.1.1.1 exos-switch#  configure vlan DHCP_Server dhcp-options dns-server secondary 8.8.8.8 Step 5. Check the DHCP configuration exos-switch#  show dhcp-server VLAN "DHCP_Server":     DHCP Address Range   : 192.168.100.10->192.168.100.200     Netlogin Lease Timer : Not configured (Default = 10 seconds)     DHCP Lease Timer     : Not configured (Default = 7200 seconds)     Default Gateway      : 192.168.100.1     Primary DNS Server   : 1.1.1.1     Secondary DNS Server : 8.8.8.8     Ports DHCP Enabled   : 1-10 Step 6. (Optional) Configure the DHCP lease timer The DHCP lease timer can be changed as follows. This example shows a change from the default 2 hours to 8 hours. Step 7. (Optional) Check the DHCP lease exos-switch#  show vlan "VLAN_NAME" dhcp-address-allocation Enabling and Disabling DHCP https://documentation.extremenetworks.com/exos_32.2/GUID-771750A3-0D4A-4358-A3D0-72B3CD7518AE.shtml DHCP  is enabled on a per port, per  VLAN  basis. Enable or disable DHCP on a port in a VLAN using the commands: enable dhcp ports  port_list   vlan   vlan_name disable dhcp ports  port_list   vlan   vlan_name Displaying VLAN information https://documentation.extremenetworks.com/slxos/sw/20xx/l2config/GUID-D12CCE42-5F55-4DCC-8C83-CBD009CEEF0B.shtml Do the following to display information about a specific VLAN.
