[Linux-PowerEdge] Advice on spanning tree

Hi Deller's,

I'm hoping to get our switch stacks resilient to a single switch 
failure, we currently have this:-

Key:
----  = fibre
+++  = stacking
"""""    = cat5
[??? ]   = switch

Internet                                          Internet
"                                                      "
"                                                      "
[xa          ]  ------xfp 10g ----   [ yi              ]
[ 6248     ]  ------1g ---------  [ 6248        ]
+           "                                      +             "
+           "                                      +             "
+           "                                      +             "
[6248     "  ]                                   [6248      "    ]
          "     "                                          "        "
          "     "                                          "        "
[xg    "     " ]                                   [yh "        "     ]
[6248      " ]                                   [6248     "      ]
+           "                                        +           "
+           "                                        +           "
[6248        ]                                    [6248         ]


So the proposed change is to add another 10g link between xg and yh

At the moment the spanning tree config is:-

xa

spanning-tree mode mstp
spanning-tree mst configuration
name "00-1E-C9-97-29-4B"


xg


spanning-tree mode mstp

yi


spanning-tree mode mstp
spanning-tree mst configuration
name "00-1E-C9-97-2A-77"


yf

spanning-tree mode mstp


g.
