When a new ACL rule entry is added, the sequence number can be specified so that the new ACL rule entry is placed in the desired position in the access list. • The QoS Differentiated Services (DiffServ) feature allows traffic to be classified into streams and given certain QoS treatment in accordance with defined per-hop behaviors. The switch supports both IPv4 and IPv6 packet classification. • The Class of Service (CoS) queueing feature lets you directly configure certain aspects of switch queuing. This provides the desired QoS behavior for different types of network traffic when the complexities of DiffServ are not required. CoS queue characteristics, such as minimum guaranteed bandwidth and transmission rate shaping, are configurable at the queue (or port) level. You can use the following methods to manage the switch: • Use a telnet client, SSH client, or a direct console connection to access the CLI. The CLI syntax and semantics conform as much as possible to common industry practice. • Use a network management system (NMS) to manage and monitor the system through SNMP. M4500 supports SNMP v1/v2c/v3 over the UDP/IP transport protocol. • The DHCP client on the switch allows the switch to acquire information such as the IP address and default gateway from a network DHCP server. You can also disable the DHCP client and configure static network information. Other configurable network information includes a Domain Name Server (DNS), host name to IP address mapping, and a default domain name. M4500 also includes a DHCPv6 client for acquiring IPv6 addresses, prefixes, and other IPv6 network configuration information. • You can upload and download files such as configuration files and system images by using TFTP, Secure FTP (SFTP), or Secure Copy (SCP). Configuration file uploads from the switch to a server are a good way to back up the switch configuration. You can also download a configuration file from a server to the switch to restore the switch to the configuration in the downloaded file. • This feature provides a mechanism to detect the integrity of the image, if the software binary is corrupted or tampered with while end user attempts to download the software image to the switch. This release addresses this problem by using digital signatures to verify the integrity of the binary image. It also provides flexibility to download a digitally signed configuration script and verify the digital signature to ensure the integrity of the downloaded configuration file. • The Auto Install feature allows the switch to upgrade the configuration file automatically during device initialization with limited administrative configuration on the device. The switch can obtain the necessary information from a DHCP server on the network. • The Warm Reboot feature reduces the time it takes to reboot the switch thereby reducing the traffic disruption in the network during a switch reboot. For a typical switch, the traffic disruption is reduced from about two minutes for a cold reboot to about 20 seconds for a warm reboot. • The system logs events with severity codes and timestamps. The events are sent as SNMP traps to a trap recipient list. • RMON is a standard Management Information Base (MIB) that defines current and historical MAC-layer statistics and control objects, allowing real-time information to be captured across the entire network. The data collected is defined in the RMON MIB, RFC 2819 (32-bit counters), RFC 3273 (64-bit counters), and RFC 3434 (High Capacity Alarm Table). The statistics application collects the statistics at a configurable time interval. The user can specify the port number(s) or a range of ports for statistics to be displayed. The configured time interval applies to all ports. Detailed statistics are collected between the specified time range in date and time format. The time range can be defined as having an absolute time entry and/or a periodic time. For example, a user can specify the statistics to be collected and displayed between 9:00 15 OCT 2019 (START) and 21:00 15 OCT 2019 (END) or schedule it on every MON, WED and FRI 9:00 (START) to 21:00 (END). The user receives these statistics in a number of ways as listed below: • User requests through CLI for a set of counters. • User can configure the device to display statistics using syslog or email alert. The syslog or email alert messages are sent by statistics application at END time. The statistics are presented on the console at END time. Page 10 of 29
