Dell Networking 7048 Switch (Overview)

iSCSI optimization

Help save time when configuring your Internet SCSI (iSCSI) SAN. Dell Networking 7000 series switches automatically detect EqualLogic arrays and configure the switch for iSCSI environments, at both global and port levels. The 7000 series also provides information about all active iSCSI sessions to help enable easier management and optimization.

VoIP functionality

Help ensure that Voice over Internet Protocol (VoIP) traffic is prioritized, in the event of resource contention, through the voice VLAN function. LLDP-MED provides detailed network topology records, troubleshooting data and emergency call service via IP phone location information.
Robust management

Rapid deployment and configuration

Help save deployment time and costs by simplifying your network rollout with Dell Networking 7000 series Gigabit Ethernet switches. Use local USB to easily assign switch configuration, updates and addressing during initial rollout. You can also choose alternative auto-configuration options, such as Dynamic Host Configuration Protocol (DHCP).

Robust management

You'll enjoy a number of management options with Dell Networking 7000 Series switches, including:

  • A powerful and industry-standard command-line interface.
  • Remote management using an embedded web server.
  • Support for SNMP-based management applications.
  • Managing up to 600 ports from a single IP address in a stack of multiple 7000 series switches.

Automated security

Select from multiple security levels, with options that include such enterprise-class features as:

  • SSH/SSL management encryption
  • DHCP snooping
  • IP and MAC-based ACLs
  • Access password protection
  • Port-based MAC address alert and lockdown
High-level security is provided through:

  • RADIUS (RFC 2865) and TACACS+ (RFC 1492) remote authentication for switch management access
  • Management access filtering via management access profiles
Dell Networking 7000 switches can also help simplify security rollouts by enabling you to try implementation before full enforcement is enabled. This can help smoothen your transition to a secure network for your enterprise.
