    Hi,

    does a sequence have any limitations as maximun number of octets, or something else?
    If so, where could I find this information?

    Thanks in advance,

    Andre

    HI,

    Neither the SMI, PROTO definitions, or transport mapping put
    an explicit length restriction on a SEQUENCE. However, you do
    have message length limitations due to transport limitations
    and implementation limitations of agents and managers.

    What are you trying to accomplish?

    ASN.1 does not restrict a sequence. BER restricts a sequence basically
    to 2^{1016}-1 bytes, which is the following number:

    In SNMP land, things are typically restricted by the transport and the
    message buffer space used by the engines. SNMP over UDP only requires
    that engines support messages up to 484 bytes, but most of the support
    messages up to the Ethernet MTU. SNMP over TCP requires that engines
    support at least messages of 8192 bytes.
