RouterOS v3 Configuration and User Guide
instances may be send by RADIUS server to specify additional URLs which are choosen in round
robin fashion.
• Mikrotik-Advertise-Interval - Time interval between two adjacent advertisements. Multiple
attribute instances may be send by RADIUS server to specify additional intervals. All interval values
are threated as a list and are taken one-by-one for each successful advertisement. If end of list is
reached, the last value is continued to be used.
• WISPr-Redirection-URL - URL, which the clients will be redirected to after successfull login
• WISPr-Bandwidth-Min-Up - minimal datarate (CIR) provided for the client upload
• WISPr-Bandwidth-Min-Down - minimal datarate (CIR) provided for the client download
• WISPr-Bandwidth-Max-Up - maxmal datarate (MIR) provided for the client upload
• WISPr-Bandwidth-Max-Down - maxmal datarate (MIR) provided for the client download
• WISPr-Session-Terminate-Time - time, when the user should be disconnected; in "YYYY-MM-
DDThh:mm:ssTZD" form, where Y - year; M - month; D - day; T - separator symbol (must be
written between date and time); h - hour (in 24 hour format); m - minute; s - second; TZD - time
zone in one of these forms: "+hh:mm", "+hhmm", "-hh:mm", "-hhmm"
The received attributes override the default ones (set in the default profile), but if an attribute is not
received from RADIUS server, the default one is to be used.
Rate-Limit takes precedence over all other ways to specify data rate for the client. Ascend data rate
attributes are considered second; and WISPr attributes takes the last precedence.
Here are some Rate-Limit examples:
• 128k - rx-rate=128000, tx-rate=128000 (no bursts)
• 64k/128M - rx-rate=64000, tx-rate=128000000
• 64k 256k - rx/tx-rate=64000, rx/tx-burst-rate=256000, rx/tx-burst-threshold=64000, rx/tx-burst-
time=1s
• 64k/64k 256k/256k 128k/128k 10/10 - rx/tx-rate=64000, rx/tx-burst-rate=256000, rx/tx-burst-
threshold=128000, rx/tx-burst-time=10s
Accounting-Request
The accounting request carries the same attributes as Access Request, plus these ones:
• Acct-Status-Type - Start, Stop, or Interim-Update
• Acct-Authentic - either authenticated by the RADIUS or Local authority (PPPs only)
• Class - RADIUS server cookie, as received in Access-Accept
• Acct-Delay-Time - how long does the router try to send this Accounting-Request packet
Stop and Interim-Update Accounting-Request
Additionally to the accounting start request, the following messages will contain the following attributes:
• Acct-Session-Time - connection uptime in seconds
• Acct-Input-Octets - bytes received from the client
• Acct-Input-Gigawords - 4G (2^32) bytes received from the client (bits 32..63, when bits 0..31 are
delivered in Acct-Input-Octets)
• Acct-Input-Packets - nubmer of packets received from the client
• Acct-Output-Octets - bytes sent to the client
• Acct-Output-Gigawords - 4G (2^32) bytes sent to the client (bits 32..63, when bits 0..31 are
delivered in Acct-Output-Octets)
• Acct-Output-Packets - number of packets sent to the client
Stop Accounting-Request
These packets will, additionally to the Interim Update packets, have:
• Acct-Terminate-Cause - session termination cause (see RFC2866 ch. 5.10)
