DHCP Commands
Use these commands to configure DHCP features on the Switch.
• Use the dhcp relay commands to configure DHCP relay for specific VLAN.
• Use the dhcp smart-relay commands to configure DHCP relay for all broadcast
domains.
• Use the dhcp server commands to configure the Switch as a DHCP server. (This
command is available on a layer 3
Switch only.)

- Chapter 14 data center bridging commands 72
- Command summary 72
- Ethernet switch cli reference guide 72
- Pfc should be configured the same on connected switch ports if dcbx is used then one switch port must be configured to accept network configuration from the peer switch port auto if both switch ports are configured to accept configuration auto on both switch ports then the configuration of the switch port with the lowest mac address hex value sum is used 72

- Application priority 76
- Chapter 14 data center bridging commands 76

- In this example the switch relays dhcp requests for the vlan1 and vlan2 domains there is only one dhcp server for dhcp clients in both domains 81
- In this example there are two vlans vids 1 and 2 in a campus network two dhcp servers are installed to serve each vlan the switch forwards dhcp requests from the dormitory rooms vlan 1 to the dhcp server with ip address 192 68 00 dhcp requests from the academic buildings vlan 2 are sent to the other dhcp server with ip address 172 6 0 00 81
- This example shows how to configure the switch for this configuration dhcp relay agent information option 82 is also enabled 81
- Vlan1 vlan2 81
- In this example the switch is a dhcp server for clients on vlan 1 and vlan 2 the dhcp clients in vlan 1 are assigned ip addresses in the range 192 68 00 to 192 68 00 and clients on vlan 2 are assigned ip addresses in the range 172 6 0 to 172 6 30 82
- This example shows how to configure the dhcp server for vlan 1 with the configuration shown in figure 5 on page 82 it also provides the dhcp clients with the ip address of the default gateway and the dns server 82

- Chapter 58 pppoe ia commands 248

- Ethernet switch cli reference guide 248
- This example is more advanced it assumes a pppoe ia client is connected to port 2 and a pppoe ia server is connected to port 5 if we want pppoe ia to work port 2 and port 5 must be belong to the some vlan and the pppoe ia must be enabled globally and in this corresponding vlan we also need to set port 5 as trust port then the last thing we need to do is to decide which sub options the received padi padr or padt packet needs to carry here assume both circuit id and remote id should be carried 248
- This is an example of how to enable and configure pppoe ia for vlans 248
- This is an example of how to enable and disable pppoe ia on the switch 248
- This is an example of how to set a pppoe ia trust port 248
- Because we didn t assign the appended string for remote id in examples 1 and 2 the switch appends a string to carry the client s mac address as default if we want the remote id to carry the forportvlanremoteidtest information for a specific vlan on a port we can add the following configuratio 249
- Similarly we can let the circuit id carry the information which we configure 249
- The following examples show you how to configure the vendor specific tag for pppoe ia they assume there is a pppoe ia client connected to port 2 and pppoe ia server or up link port connected to port 5 249
- This is a variation of the previous one and uses the same initial setup client on port 2 server on port 5 249
- Vendor specific tag examples 249
- Additionally we can let the circuit id or remote id carry the user configured information from a specific port whose priority is less than the specific vlan on a port setting 250
- Chapter 58 pppoe ia commands 250
- Ethernet switch cli reference guide 250
- Since we didn t assign the appended string for remote id in example 1 and 2 it will carry the client s mac address as default 250

- Weighted fair queuing wfq guarantees each queue s minimum bandwidth based on its bandwidth weight portion when there is traffic congestion wfq is activated only when a port has more traffic than it can handle queues with larger weights get more guaranteed bandwidth than queues with smaller weights this queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues by default the weight for q0 is 1 for q1 is 2 for q2 is 3 and so on guaranteed bandwidth is calculated as follows 260
- Weighted round robin scheduling wrr services queues on a rotating basis and is activated only when a port has more traffic than it can handle a queue is a given an amount of bandwidth based on the queue weight value queues with larger weights get more service than queues with smaller weights this queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues and returns to queues that have not yet emptied hybrid mode wrr spq or wfq spq some switch models allow you to configure higher priority queues to use spq and use wrr or wfq for the lower level queues 260
