>Скорее это должен быть Cisco switch cluster

Настроил switch cluster

<blockquote>sm-sm7-c2960#sh cluster
Command switch for cluster "SM7"

        Redundancy:                     Disabled
        Heartbeat interval:             8
        Heartbeat hold-time:            80

</blockquote>

<blockquote>sm-sm7-c2960#sh cluster members
                                                |---Upstream---|

на втором свиче:
<blockquote>sm-c2960_1-sm7#sh cluster

При попытке зайти на второй свич, выдает :

<blockquote>sm-sm7-c2960#rc 1
% Authorization failed.

</blockquote>
