Management
•
Management interface control: provides
management access through a modem port and
terminal interface, as well as in-band and
out-of-band Ethernet ports; provides access through
terminal interface, telnet, or Secure Shell (SSH)
•
Industry-standard CLI with a hierarchical
structure: reduces training time and expenses,
and increases productivity in multivendor
installations
•
Management security: multiple privilege levels
with password protection restrict access to critical
configuration commands; ACLs provide telnet and
SNMP access; local and remote syslog capabilities
allow logging of all access
•
SNMPv1, v2, and v3: provide complete support
of SNMP; provide full support of industry-standard
Management Information Base (MIB) plus private
extensions; SNMPv3 supports increased security
using encryption
•
sFlow (RFC 3176): provides scalable ASIC-based
wire-speed network monitoring and accounting with
no impact on network performance; this allows
network operators to gather a variety of
sophisticated network statistics and information for
capacity planning and real-time network monitoring
purposes
•
Remote monitoring (RMON): uses standard
SNMP to monitor essential network functions;
supports events, alarm, history, and statistics group
plus a private alarm extension group
•
FTP, TFTP, and SFTP support: FTP allows
bidirectional transfers over a TCP/IP network and is
used for configuration updates; Trivial FTP is a
simpler method using User Datagram Protocol (UDP)
•
Debug and sampler utility: supports ping and
traceroute for both IPv4 and IPv6
•
Network Time Protocol (NTP): synchronizes
timekeeping among distributed time servers and
clients; keeps consistent timekeeping among all
clock-dependent devices within the network so that
the devices can provide diverse applications based
on the consistent time
•
Network Quality Analyzer (NQA): analyzes
network performance and service quality by sending
test packets, and provides network performance and
service quality parameters such as jitter, TCP, or FTP
connection delays and file transfer rates; allows a
network manager to determine overall network
performance and to diagnose and locate network
congestion points or failures
•
Info center: provides a central information center
for system and network information; aggregates all
logs, traps, and debugging information generated
by the system and maintains them in order of
severity; outputs the network information to multiple
channels based on user-defined rules
•
IEEE 802.1AB Link Layer Discovery Protocol
(LLDP): automated device discovery protocol
provides easy mapping of network management
applications
•
Dual flash images: provide independent primary
and secondary operating system files for backup
while upgrading
•
Multiple configuration files: can be stored to
the flash image
Connectivity
•
High-density port connectivity: up to 10
interface module slots; up to 84 10-GbE ports, 480
Fiber Gigabit ports, or 480 PoE-enabled ports per
7500 series system
•
Jumbo frames: up to 9216 bytes allow
high-performance backups and disaster-recovery
systems
•
Loopback: supports internal loopback testing for
maintenance purposes and an increase in
availability; loopback detection protects against
incorrect cabling or network configurations and can
be enabled on a per-port or per-VLAN basis for
added flexibility
•
Ethernet OAM: provides a Layer 2 link
performance and fault detection monitoring tool,
which reduces failover and network convergence
times
•
Flexible port selection: 100/1000BASE-X auto
speed selection, 10/100/1000BASE-T auto speed
detection, plus auto duplex and MDI/MDI-X
•
Monitor link: collects statistics on performance
and errors on physical links, increasing system
availability
•
IEEE 802.3af Power over Ethernet (PoE):
provides up to 15.4 W per port to IEEE
802.3af-compliant PoE-powered devices such as IP
phones, wireless access points, and security
cameras
•
Dual-personality functionality: includes four
10/100/1000 ports or SFP slots for optional fiber
connectivity such as Gigabit-SX, -LX, and -LH, or
100-FX
