Deploying the Dell PowerConnect 8100 with the Cisco Catalyst
Consult the User Guides for each device for more information on bridge priority settings.
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
This option is less desirable because it requires migrating exiting Cisco devices over to MST, which were previously running a Cisco proprietary spanning tree protocol (PVST+ or RPVST+). Such a migration would typically require some reconfiguration and possible topology redesign. Consult the User Guides for your devices on how to set up MST.
Cisco proprietary protocols
Network administrators often run into problems receiving multiple Cisco proprietary protocols on standards based switches, which causes unexpected results on the network. Therefore, Dell PowerConnect has developed an easy way to block Cisco protocols as necessary. By creating
console(config)#interface gi1/0/3
The no
In the same way, administrators can block the other proprietary protocol packets individually (cdp, vtp, dtp, pagp, udld, sstp) as shown below replacing the ( ) with the keyword:
console(config)#interface gi1/0/3
-options put in place of parenthesis
blockcdp blocks all cdp packets on this interface
blockvtp blocks all vtp packets on this interface
blockdtp blocks all dtp packets on this interface blockpagp blocks all pagp packets on this interface blockudld blocks all udld packets on this interface blocksstp blocks all sstp packets on this interface
blockall blocks all cisco proprietary protocols on this interface
Use one or more of these filters on each port by running a mix of options on a single line, (for example,
Note: These interface ACLs take precedence over any global configuration that may be active on the switch (for example, if a form of CDP is globally running on the switch, the
