SNMP traps are sent when the following events occur:
• multiplexer power-up or reload – the 'COLD START' trap;
• unauthorized access attempt over the SNMP protocol – the 'AUTHENTICATION
FAILURE' trap;
• loss of signal or cycle synchronization on the link – the 'LINK DOWN' trap;
• switch of the link to the normal mode – the 'LINK UP' trap;
• loss of signal at the E1 port – the 'PORT DOWN' trap;
• appearance of signal at the E1 port – the 'PORT UP' trap.
5.2. Management information blocks (MIBs)
The following management information blocks (MIBs) are implemented in the multiplex-
er:
• RFC1213 (MIB-II) – a standard management information block, including common
system parameters (system), network interfaces (if), the IP protocol (ip, icmp), the
UDP protocol (udp), and SNMP protocol statistics (snmp);
• CRONYX-FMUX-MIB – a specialized management information block, containing
the states of E1 ports and of the link.
The CRONYX-FMUX-MIB management information block specification files are avail-
able from the www.cronyx.ru website.
