Gruppo attività di sola lettura
Configurazione
Per creare utenti su Aggregation Services Router 9000 (ASR9K) con accesso in sola lettura, è necessario definire un gruppo di operazioni con privilegi di sola lettura, creare un gruppo di utenti con tale gruppo di operazioni, quindi collegare il gruppo appena creato agli utenti.
Creare il gruppo di task
Queste sono le attività per le quali l'utente può eseguire i comandi show.

Crea il gruppo di utenti
I gruppi di task vengono applicati ai gruppi di utenti. È stato creato un gruppo di utenti denominato usergroup_read_only
RP/0/RSP1/CPU0:ASR9000# show run usergroup usergroup_read_only usergroup usergroup_ready_only taskgroup taskgroup_read_only ! end-group
Opzione 1. Crea utente locale
Creare un utente locale e applicare il gruppo di utenti.
RP/0/RSP1/CPU0:ASR9000# show run username tyler username tyler group usergroup_read_only secret 5 $1$wTwU$CdHKzfRJlJ7kDvJa7NWdi. !
Verifica
Mostra funzionamento comandi
RP/0/RSP1/CPU0:ASR9000# show clock 13:42:03.811 UTC Thu Jun 30 2016

Tentativi di configurazione non riusciti
Non è possibile bloccare l'accesso per la configurazione, ma qualsiasi tentativo di configurazione avrà esito negativo.
Una configurazione di base come la creazione di un'interfaccia di loopback ha esito negativo.
RP/0/RSP1/CPU0:ASR9000# conf t
RP/0/RSP1/CPU0:ASR9000(config)# int loopback 103
% This command is not authorized
Anche la rimozione di BGP ha esito negativo.
RP/0/RSP1/CPU0:ASR9000# configure
RP/0/RSP1/CPU0:ASR9000(config)# no router bgp 65530
% This command is not authorized
Verifica dell'assegnazione del gruppo
L'utente connesso è un membro di usergroup_read_only
RP/0/RSP1/CPU0:ASR9000# show user group usergroup_read_only
Controllo assegnazione attività
Questo utente ha accesso solo a READ per le attività specificate.
RP/0/RSP1/CPU0:ASR9000# show user tasks Task: aaa : READ Task: acl : READ Task: admin : READ Task: ancp : READ Task: atm : READ Task: basic-services : READ Task: bcdl : READ Task: bfd : READ Task: bgp : READ Task: boot : READ Task: bundle : READ Task: call-home : READ Task: cdp : READ Task: cef : READ Task: cgn : READ Task: config-mgmt : READ Task: config-services : READ Task: crypto : READ Task: diag : READ Task: drivers : READ Task: dwdm : READ Task: eem : READ Task: eigrp : READ Task: ethernet-services : READ Task: ext-access : READ Task: fabric : READ Task: fault-mgr : READ Task: filesystem : READ Task: firewall : READ Task: fr : READ Task: hdlc : READ Task: host-services : READ Task: hsrp : READ Task: interface : READ Task: inventory : READ Task: ip-services : READ Task: ipv4 : READ Task: ipv6 : READ Task: isis : READ Task: l2vpn : READ Task: li : READ Task: lisp : READ Task: logging : READ Task: lpts : READ Task: monitor : READ Task: mpls-ldp : READ Task: mpls-static : READ Task: mpls-te : READ Task: multicast : READ Task: netflow : READ Task: network : READ Task: nps : READ Task: ospf : READ Task: ouni : READ Task: pbr : READ Task: pkg-mgmt : READ Task: pos-dpt : READ Task: ppp : READ Task: qos : READ Task: rcmd : READ Task: rib : READ Task: rip : READ Task: route-map : READ Task: route-policy : READ Task: sbc : READ Task: snmp : READ Task: sonet-sdh : READ Task: static : READ Task: sysmgr : READ Task: system : READ Task: transport : READ Task: tty-access : READ Task: tunnel : READ Task: vlan : READ Task: vpdn : READ Task: vrrp : READ
