SmartPanel 5 SmartPanel Introduction The 1Gb Intelligent L2 Switch provides t wo switch mo des: The conventional L2 s witch mode, and SmartPanel mode. The switch can store up to two different soft ware image, called imag e1 and image2.
SmartPanel 6 Management Network The 1Gb Intelligent L2 Switch is a S witch Module within the Blade Enclosure. T he Blade Enclosure includ es an Enclosure Manager Card which manages the modules and CPU Blad es in the enclosure.
SmartPanel 7 Setting an IP address To access the switch via a Telnet, an SSH connection, or an HTT P connection, you need to have an Int ernet Protocol (IP) address set for the switch. You can assign t he IP address only to the manag ement interfac e (interface 256), associated with port 19.
SmartPanel 8 Table 3 User access levels User account Description and tasks performed user The user has no direct responsibilit y for switch management. He or she can view all switch status information and statistics, but cannot make any configur ation changes to the switch.
Browser-based interface 9 Browser-based interface Introduction This chapter explains ho w to access the switch browse r-based interface (BBI) for t he SmartPanel and config ure the swi tch.
Browser-based interface 10 If the switch IP interface address has a name on your local domain name s erver, you can enter the name instead. Using Internet Explor er, you can ent er the follo wing: 3. Log in to the switch. If your switch and browser are properly configured, you will be asked to enter a password.
Browser-based interface 11 There are three main regions on the screen. • The Port Status Area is used to view port status. Click a port icon to vie w details. • The Menu Area is used to select parti cular items or features to act upon. • The Configuration Area is use d to configure selected items.
Browser-based interface 12 Displays I/O bay number Click to expand or contact Click to select Menu Area The Menu Area is used for selecting a partic ular feature to act upon. Configuration forms for the selected item appear in the Configuration Window.
Browser-based interface 13 Port Group Mapping SmartPanel ports can be combined into Port Groups. Up to five Port Groups are availab le in the SmartPanel. A Spare Ports Group is available for unused ports. VLANs and Link Aggregation Groups (tr unks ) are config ured automatically fo r each Port Group.
Browser-based interface 14 In this example, Port 1-4, 20-21 are assigned to Group1, and Port 5-8, 22- 23 are ass igned to Group2. The others are assigned to Spare Ports Group. Internal Port Settings On the BBI, choose Internal Port Settings to enable or disable the serv er blad e port.
Browser-based interface 15 External Port Settings On the BBI, choose External Port Setti ngs to configure the external port. The following table describes the external port configuration. Table 7 External Port Settings Command Description Port Name Sets a name for the port.
Browser-based interface 16 VLAN Virtual LANs (VLANs) are commonly used to split up gr ou ps of network users into manageable br oadcast domains, to create logical segmentation of workgroups, and to enforce security polici es among logical segments. T his s witch supports up to 1,000 VLANs per switch.
Browser-based interface 17 Non-Default Virtual LANs On the BBI, choose Non-Default Virtual LANs to create VLANs and assign them to Port Groups. T he non-default VLAN ID is placed in the frame header of a packet in for watding from the port. The following describes the steps to add VLAN ID.
Browser-based interface 18 3. Select the corresponding radi o button to assign the VLAN to a Port Group. 4. Click Apply to make the changes active. Management On the BBI, choose System Settings > Management to c onfigure SNMP System Settings and System Log Server Settings.
Browser-based interface 19 Table 8 Management Command Description Facility of Secondary Server This option sets the fac ility level of the secondary syslog server displayed. The default is 0. Local User Administration On the BBI, choose System Settings > Local Us er Administration to configure the user.
Browser-based interface 20 Remote User Administration On the BBI, choose System Settings > Remote User Admi nistration to configure the RADIUS server or the TACACS+ server.
Browser-based interface 21 Ti m e S e r v i c e s On the BBI, choose System Settings > Time Services to configure the NTP server. The following table descri bes the configurati on. Table 11 Time Services Command Description General Settings Current Date Configures the system date.
Browser-based interface 22 T runking Trunk groups provide super- bandwidth, multi-link connecti ons bet ween SmartPanel or other trunk-cap able devices. A trunk group is a group of ports that act together, combini ng their bandwidth to create a singl e, larger virtual link.
Browser-based interface 23 Trunk Group configuration On the BBI, choose System Settings > Uplink/Group to enabl e or disab le the Link Aggr egation Control P rotocol. When enabled, the exter nal ports are configured as a LAC P trunk group. When disabl ed , they are configured as a static trunk group.
Browser-based interface 24 Failover configuration On the BBI, choose System Settings > Uplink/Group to conf igure the S witch Failover and Number of Links to Trigger Failover. IGMP Snooping IGMP Snooping allows the SmartPanel to for ward multicas t traffic only to those ports that request it.
Browser-based interface 25 Boot Management On the BBI, choose System Settings > Boot Management to backup or restore the switch configuration , update the switch software image, or get dump file. The following table descri bes the configurati on. Table 12 Boot Management Command Description Reboot the Module button Reboots the switch.
Browser-based interface 26 Table 12 Boot Management Command Description Put TS Dump Uploads the TS (tech support) dump file to the TFTP or FTP server specified in Remote File Name. Put Crash Dump Uploads the core (PANIC) dump fi le to the TFTP or FTP server specified in Remote Filename.
