Use the no form of this command to return to the default setting.
Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands srr-queue bandwidth shape Examples This example shows how to configure the queues for the same port for both shaping and sharing. Because the weight ratios for queues 2, 3, and 4 are set to 0, these queues operate in shared mode. The bandwidth weight for queue 1 is 1/8, which is 12.5 percent.
Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands srr-queue bandwidth share srr-queue bandwidth share Use the srr-queue bandwidth share interface configuration command switch to assign the shared weights and to enable bandwidth sharing on the four egress queues mapped to a port.

The range is 0.0 to 10000000000.0. Block the flooding of storm packets when the value specified for pps is reached. • pps-low—(Optional) Falling suppression level, up to 1 decimal place. The range is 0.0 to 10000000000.0.
Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands storm-control If you configure the action to be taken as shutdown (the port is error-disabled during a storm) when a packet storm is detected, you must use the no shutdown interface configuration command to bring the interface out of this state. If you do not specify the shutdown action, specify the action as trap (the switch generates a trap when a storm is detected).
Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands switchport access switchport access Use the switchport access interface configuration command to configure a port as a static-access or dynamic-access port. If the switchport mode is set to access, the port operates as a member of the specified VLAN. If set to dynamic, the port starts discovery of VLAN assignment based on the incoming packets it receives.
Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands switchport access These restrictions apply to dynamic-access ports: • The software implements the VLAN Query Protocol (VQP) client, which can query a VMPS such as a Catalyst 6000 series switch. The Cisco Catalyst Blade Switches are not VMPS servers. The VMPS server must be configured before a port is configured as dynamic. • Use dynamic-access ports only to connect end stations.
