The following example configures a shape entity with CIR of 128 kbps and sets the lower bound CIR to 64 kbps when BECNs are received:

policy-map dts-p2p-all-action
class class-p2p-all
shape average 128000
shape adaptive 64000

If the traffic being sent to the network must strictly conform to the configured network provisioned CIR, then you should use average traffic shaping.

The following example sets the uses average rate

shaping to ensure a bandwidth of 256 kbps:

shape average 256000

The following example uses peak rate shaping to ensure a bandwidth of 300 kbps but allow throughput up to 512 kbps if enough bandwidth is available on the interface:

bandwidth 300

shape peak 512000

The following example configures traffic shaping using an average shaping rate on the basis of a percentage of bandwidth. In this example, 25 percent of the bandwidth has been specified.  Additionally, an optional be value and bc value (100 ms and 400 ms, respectively) have been specified.

Router> enable
Router# configure terminal
Router(config)# policy-map policy1
Router(config-pmap)# class-map class1
Router(config-pmap-c)# shape average percent 25 20 ms
be 100 ms bc 400 ms
Router(config-pmap-c)# end

Lab 1 & 2 notes.

I put in about 10 hours of study time today. I came across a few commands I have not seen/used before.

switchcore wirespeed-store = “to reserve bandwidth for buffer storage to accommodate broadcast and multicast storms.”

*** The spanning-tree portfast bpdufilter command enables BPDU filtering globally on PortFast ports.  BPDU filtering prevents a port from sending or receiving any BPDUs. ( if a port is configured for portfast and it receives a BPDU portfast will be removed.)

You can override the effects of the portfast bpdufilter default command by configuring BPDU filtering at the interface level.

Note Be careful when enabling BPDU filtering. The feature’s functionality is different when you enable it on a per-port basis or globally. When enabled globally, BPDU filtering is applied only on ports that are in an operational PortFast state. Ports send a few BPDUs at linkup before they effectively filter outbound BPDUs. If a BPDU is received on an edge port, it immediately loses its operational PortFast status and BPDU filtering is disabled.

When enabled locally on a port, BPDU filtering prevents the Catalyst 6500 series switch from receiving or sending BPDUs on this port.

Caution Be careful when using this command. Using this command incorrectly can cause bridging loops.

vlan dot1q tag native = To enable dot1q (802.1Q) tagging for all VLANs in a trunk, use the vlan dot1q tag native command in global configuration mode ( send the VLAN ID across trunks)

gotchas:

1. when setting up etherchannels shut the interfaces down, config and then enable the interfaces.
2. troubleshooting in the lab: do a show run and look for stuff that does not belong there, like VALC’s!
3. all vtps passwords are md5
4. with some ios’s port-channels must match
5. req: every packet that traverses the trunk must have the VLAN ID. solution: vlan dot1q tag native.
6. spanning-tree portfast bpdufilter enable (global) if a port is configured for portfast and it receives a BPDU it will lose its portfast status.
