54 Simple Network Management Protocol (SNMP) and Syslog This chapter contains commands to configure and monitor the simple network management protocol (SNMP) v1/v2/v3 and Syslog. The chapter contains the following sections: • SNMP Commands • Syslog Commands SNMP Commands The following SNMP commands are available in the Dell Networking operating software. The simple network management protocol (SNMP) is used to communicate management information between the network management stations and the agents in the network elements. The system supports SNMP versions 1, 2c, and 3, supporting both read-only and read-write modes. The system sends SNMP traps, which are messages informing an SNMP management system about the network. The system supports up to 16 SNMP trap receivers. Important Points to Remember • Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient for both LAN and WAN applications. If you experience a timeout with these values, the recommended best practice on Dell Networking switches (to accommodate their high port density) is to increase the timeout and retry values on your SNMP server to the following: - SNMP Timeout - greater than 3 seconds. - SNMP Retry count - greater than 2 seconds. • If you want to query an E-Series switch using SNMP v1/v2/v3 with an IPv6 address, configure the IPv6 address on a non-management port on the switch. • If you want to send SNMP v1/v2/v3 traps from an E-Series using an IPv6 address, use a nonmanagement port. • SNMP v3 informs are not currently supported with IPv6 addresses. • If you are using access control lists (ACLs) in an SNMP v3 configuration, group ACL overrides user ACL if the user is part of that group. • SNMP operations are not supported on a virtual local area network (VLAN). 1908 Simple Network Management Protocol (SNMP) and Syslog
