Data center bridging commands 71

Hapter 71

Overview 71

Pfc ets and dcbx standards 71

Application priority is used to globally assign a priority to all fcoe traffic on the switch dcbx data center bridging capability exchange ieee 802 qaz 2011 uses lldp link layer discovery protocol to advertize pfc ets and application priority information between switches pfc information should be consistent between connected switches so pfc can be configured automatically using dcbx 72

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

Chapter 14 data center bridging commands 73

Ethernet switch cli reference guide 73

In the following example pfc on switch a port 1 is set to auto so that it can accept the priority configuration from the peer switch b if switch a did not receive pfc pdu from switch b then priority 2 will be used by switch a 73

In the following example switch a is not using switch b s configured priorities 73

In the following example switch a is using switch b s configured priorities 73

Pfc command examples 73

The guaranteed minimum bandwidth for both san and lan traffic is 2 gbps with a link bandwidth of 10gbps 75

This is an example where the non editable default traffic class id 0 uses sp queuing lan and san traffic uses wfq queuing with equal weighting of 50 each 75

Application priority 76

Chapter 14 data center bridging commands 76

Ethernet switch cli reference guide 76

Next configure a port for traffic class es and bind priorities to traffic classes on a port in the next example we configure port 1 and bind priorities 0 1 and 2 to traffic class 2 lan 3 4 5 and 6 to class 1 san and 7 to class 0 the default traffic class 76

Use the application priority command to assign a priority to all fcoe traffic on a switch 76

Application priority can then be used in conjunction with ets and pfc as shown in the following examples 77

Application priority command examples 77

Chapter 14 data center bridging commands 77

Default traffic class 0 with strict priority for priorities 0 1 2 6 7 traffic class 3 for legacy ethernet traffic guarantee bandwidth 40 for priority 4 5 traffic class 4 for fcoe traffic guarantee bandwidth 60 for priority 3 unicast to non unicast weight ratio is 100 100 77

This is an application priority command example with pfc 77

Chapter 14 data center bridging commands 78

Dcbx uses lldp link layer discovery protocol to exchange pfc ets and application priority information between switches pfc information should be consistent between switches so this can be configured automatically using dcbx 78

Ethernet switch cli reference guide 78

In order for switches to exchange information they must send their type length values tlvs in order to be able to read each other s information 78

Figure 3 example global dhcp relay 81

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

How you access the switch using http varies depending on the operating system os and the type of browser you use and the type of address you want to access 171

Ipv6 is installed and enabled by default in windows vista use the ipconfig command to check your automatic configured ipv6 address as well you should see at least one ipv6 address available for the interface on your computer 171

It s recommended to use internet explorer 7 or firefox to access the switch s web gui 171

Make sure you have enabled ipv6 on your computer see section 35 use the ipconfig command in the command prompt to check the ipv6 address on your computer the example uses an interface with address fe80 2d0 59ff feb8 103c to 171

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

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

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
