Yes, it's part of the extended host name syntax:
        Extended Host Name Syntax
        
        In all places where ``community at router'' is accepted, you can
        add additional parameters for the SNMP communication using
        colon-separated suffixes. You can also append a pipe symbol
        ( | ) and the name of a numeric conversion subroutine as
        described under the global keyword "ConversionCode" above. The
        full syntax is as follows:
        
        community at router[:[port][:[timeout][:[retries][:[backoff][:[version]][|name]]]]]
        
        
        where the meaning of each parameter is as follows:
        
port
        
        the UDP port under which to contact the SNMP agent (default:
        161)
        
        The complete syntax of the port parameter is 
        
        remote_port[!local_address[!local_port]]
        
        
        Some machines have additional security features that only allow
        SNMP queries to come from certain IP addresses. If the host
        doing the query has multiple interface, it may be necessary to
        specify the interface the query should come from.
        
        The port parameter allows the specification of the port of the
        machine being queried. In addition, the IP address (or hostname)
        and port of the machine doing the query may be specified.
        
        Examples:
        
        somehost
         somehost:161
         somehost:161!192.168.2.4!4000 use 192.168.2.4 and port 4000 as source
         somehost:!192.168.2.4 use 192.168.2.4 as source
         somehost:!!4000 use port 4000 as source
