Deploying the Dell PowerConnect 8100 with the Cisco Catalyst Introduction New demanding campus workloads are compelling Network administrators to take another look at the campus core/aggregation layers. The existing products like Cisco Catalyst 6500 platforms are aging and cannot support the new deployments. Network administrators are exploring options to either reposition the existing gear or replace it. Therefore, it is critical to understand how the newer campus aggregation/core

Deploying the Dell PowerConnect 8100 with the Cisco Catalyst There are a couple of key differences between the Dell PowerConnect 8100 and the Cisco Catalyst: • Ports on the Cisco Catalyst are in shut mode by default, whereas ports on the PowerConnect are active (no shut) by default. To use a Catalyst port, enable it with the no shut command. • The Dell PowerConnect 8100 is in Layer 2 mode by default whereas the Cisco Catalyst is in Layer 3. The switchport command is required to put

Deploying the Dell PowerConnect 8100 with the Cisco Catalyst In-band management traffic is mixed in with production network traffic, and is subject to all of the filtering rules applied on a switched/routed port such as ACLs and VLAN tagging. See the Dell PowerConnect 8100 User Guide for more information on OOB versus Management VLAN. The Cisco Catalyst uses a similar setting known as SVI (switch virtual interface) to do remote switch management. When activated, an SVI is used only f

Deploying the Dell PowerConnect 8100 with the Cisco Catalyst RSTP (Based on IEEE 802.1w) - Rapid STP. A standards-based protocol that is considerably faster at network convergence (after a topology change) than its STP predecessor in most network implementations. It is the default for the Dell PowerConnect 8100, and is compatible with STP. MST (Based on IEEE 802.1s) – Multiple Spanning Tree protocol or MSTP. Allows for multiple instances of spanning tree across a network. Each inst

Method 2: MSTP In addition, users can minimize downtimes by using a standard protocol on the Cisco Catalyst. Spanning tree modes available on the Cisco Catalyst WS-C6504-E with IOS 12.2(33)SXI4a are MST, PVST, and Rapid-PVST. Of the three, only MST is an IEEE standard protocol. MST is also the only protocol available on both
