To begin, click the LAN tab and then click LAN Uplinks Manager.In the LAN Uplinks Manager, click VLANs, then VLAN Manager, and then Fabric A. 2011 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information.Page 6 of 12
Step 1. Define VLANs globally or reuse the existing VLANs.When VLANs are newly created and do not have specific uplinks associated, these VLANs will flow on all uplinks.Step 2. Define uplinks on Fabrics A and B. 2011 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information.Page 7 of 12
Step 3. Assign uplinks to VLANs.Select the uplink interface in the left pane and then the VLANs in the right pane.Click Add to VLAN to add the selected uplinks to the VLANs.Note:VLANs flow only on selected uplinks, not on the rest of the uplinks.Follow the same procedure for Fabric B.Click Save to save the configuration and make it effective. 2011 Cisco and/or its affiliates.

Removing VLAN MembershipWhen the last uplink is removed from a VLAN, since no specific uplink is assigned to this VLAN, it inherits thedefault behavior of the VLAN everywhere and flows on all uplinks. The recommended approach is to remove allunused VLANs from the system.Note:VLAN 1 still is present on all uplinks and needs to be removed from the upstream switches.The port designated for multicast and broadcast traffic on a VLAN basis can be queried through the command-line interface (CLI) in the Cisco NX-OS Software:UCS (nxos)# show platform software enm internal info vlandb id 11vlan id 11------------Designated receiver: Eth1/13Membership:Eth1/13Exceptions and Error HandlingThe user must be sure to correctly configure the VLAN on uplinks and vNICs because if the configuration is notcorrect, vNIC pinning failure may occur. The actions described here are taken in the event of errors.Single VLAN on a vNIC (No Trunk)If an invalid pin group is specified (that is, if the VLAN does not exist on the uplink specified in the pin group), thestatic pin group configuration is applied, the vNIC stays up, and traffic is discarded. A configuration error is flaggedin the Status pane as shown in Figure 5. 2011 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information.Page 9 of 12
Figure 5.Configuration Error Flagged in the Status PaneMultiple VLANs on a vNIC (Soft Switch Scenario)If a vNIC is defined to carry VLANs belonging to two separate disjoint Layer 2 upstream networks, pinning will fail,and a fault will be raised.For example, in the topology in Figure 6, if a vNIC is defined to carry VLANs 10 through 25 in the service profile,pinning will fail because no uplink matches the pinning criteria. 2011 Cisco and/or its affiliates.

MAC address learning occurs only on the server ports and appliance ports MAC address aging is not supported; MAC address changes are fully supported Active-active links are used regardless of the number of uplink switches The solution is highly scalable because the control plane is not occupied All uplink
General Constrained Shortest k-Disjoint Paths (GCSDP(k)) Problem: Given two nodes s and t and a positive integer T, the GCSDP(k) problem is to find a set of k(k ‚ 2) link-disjoint s-t paths p1;p2:::;pk such that the delay of each path pi is at most T and the total cost of the k paths is minimum. Constrained Shortest k-Disjoint Paths (CSDP(k .
MPLS, designed to scale IP networks, is a natural choice for virtual private networks. Supporting multiple private networks on a shared infrastructure suggests immediate scaling problems for both Layer 3 and Layer 2 networks. On a Layer 3 network, asking each router on the network to potentially
9. Build a sugar-cube pyramid as follows: First make a 5 5 1 bottom layer. Then center a 4 4 1 layer on the rst layer, center a 3 3 1 layer on the second layer, and center a 2 2 1 layer on the third layer. The fth layer is a single 1 1 1 cube. Express the volume of this pyramid as a percentage of the volume of a 5 5 5 cube. 10.

Layer 0 is a special layer provided in the AutoCAD program. You cannot rename or delete layer 0 from the list of layers. Layer 0 has special properties when used with the Block and Insert commands, which are covered in Tutorial 10. Layer POINTS is the current layer in mysubdivis.dwg. There can be only one current layer at a time.
