2960S stack Member priorities

• 2960S - no connectivity to interface fa0 mgmgt?

  Hi people,

  I'll try to make this short!

  I have a pair of 2960S stacked (LAN basic WS-C2960S-48TS-L to be exact) toggle 12.2 running (58) SE2 configured with multiple VLANs.  No of them have VLAN interfaces active L3 and the switch can therefore be managed by the management port fa0 (via https/ssh) and the console.

  The problem I have is the fa0 connectivity fails, depending on where I'm ping of. For example:

  Port 2960 (fa0) MGMGT--> switch upstream<-- 2960's="" vlan="" 100="" (gi1/0/26)=""><-- client="">

  |

  |

  Rest of LAN

  Pings to fa0 LAN or switch upstream - PASS

  Pings to fa0 VLAN100 customers - FAIL

  Pings to rest of LAN of VLAN 100 customer - PASS

  Lets say we extend the above as follows:

  Port 2960 (fa0) MGMGT--> switch upstream<-- 2960_vlan_100="" (gi1/0/26)="" |="" 2960_vlan_100="" (gi1/0/28)=""><-- downstream="" switch=""><--  dsktp="">

  |

  |

  Rest of LAN

  Same results as the initial installation, but additionally:

  Pings to fa0 customer switch downstream - FAIL

  Pings to rest of LAN switch/clients downstream - PASS

  So I think that what is happening is that the 2960 detects fa0 MAC resolves to one of its own interface addresses and therefore do not pass traffic on the switch upstream.  The end result is that the traffic never reaches fa0.  Could someone please confirm if my reasoning is correct here?  And is it possible around this installation problem?

  I have attached my configs in a zip if it helps.

  Thank you very much

  Alistair

  EDIT: I would also add that the ARP entries for fa0 are present and correct in the ARP tables to downstream customers.

  Edit2: Added 'loopback' command to fa0 with no luck and downloaded Windows EOL RC

  Hey, Alistair,.

  I believe that the best route to effective management would be to assign an IP address accessible to an available LAN VIRTUAL interface, configure your settings vty and disable Fa0. If security is an issue, you can always also set specific security settings.

  Hope this suggestion helped!

  Thank you

• Stackable inter-serie

  Hello

  Before you start left exercise me the by official "help I'm not a network guy" sentence!

  I just bought 2 x N2048 L2 switch with stacking cables. I need to configure these to work with an existing pile of L3 PC 6224. 6224 battery has 2 x 10GB sfp module links and is configured as an access and management with all VLAN resulted them in a firewall.

  the order of for the States of N2048 (not stacking inter series) stacking is very different between these 2 switches is not surprising - so it seems I should these LAG? -What would look like this?

  Thank you and all my apologies if this is very blurry

  Rob.

  Hi, Rob!

  The LAG (aggregation of links) is simply two or more cables of connection between two network devices. A single cable connection can also work, but using several cables can provide higher availability (backup in case where a cable/port breaks down) and higher bandwidth.   GAL (also known as the Group of channels or channels of port) can be created through 2 or more ports of the switches of members different battery.

  In your case, it seems that you want to move forward and to stack your switches N2000 using cables stacking that came with them.  Once this is done, you can use two or more cables to connect the two batteries.  Each stack will look like a single switch to any other network device that connects to it. Each of your stacks think so in this case, that it only connects to another switch even if it is actually connected to another battery (multiple switches).

  For high availability, plug a cable in a stack member (any port) and the second into a second member of the same stack stack (any port) is the best practice.  Do the same for the other battery when connecting the two batteries.  In this way, if a member breaks down, connectivitiy between two batteries will stay up.   This example is just using an OFFSET of 2-port, but the same thing could be done if you use more ports.

• The problems of routing VLAN?

  Hello

  I'm trying to get our network out of a topology of flat to work with the hardware I have on the spot I have setup the network and local networks virtual, but could not get any other VLAN to carry. Here is what I use:

  Reference Dell PowerConnect 6248 as my router from Layer 3 and three PowerConnect 2748 detach the 6248 in three GAL groups all with four ports together. I have VLAN 10-50 for various average things regime 192.168.10.0/24, 192.168.20.0/24, 192.168.30.0/24 ect.

  Here's the question: 10.0 network works fine, but on any other VLAN, I get an IP address from the DHCP server, but I can't ping my gateway let alone ping another VLAN.

• Replace the battery. Reference Dell 6248

  Hello!

  We have a set of three Dell Powerconnect 6248 switches.

  One of the switches must be replaced with the new one (same model).

  the well known "pwcnt_stacking_switches.pdf" document does not say how to replace a member of the battery,

  just how to add additional, or to remove switch a.

  It is said in the documentation for the 3524 powerconnect switches:

  Exchange of stacking of members
  If a member of the stack with the same unit ID replaces an existing UnitID with the same ID of the unit, the
  the previous device configuration is applied to the inserted stack Member

  Even apply to 6248? This approach works?

  How a stand-alone switch can be prepared to be added to the stack as some number of particular unit (excluding implementation stack-port mode battery)?

  is it

  Renumber (conf) #switch

  ?

  Yes, guess I replace unit Number or number 2. (out of three)

  Once I have remove the old unit 2 and insert a new one, the new switch will get UnitID = 4.

  After I using renumber

  switch 4 renumber 2

  He will get all the previously attributed to the old switch 2 port configuration?

• 2960 - S FlexStack - stack integration issue?

  I have a client with two features of WS-C2960S-24PD-L, both devices have Flexstack modules and run a software C2960S (C2960S-UNIVERSALK9-M), Version 12.2 (55) SE2, VERSION of the IOS SOFTWARE (fc1).

  The first switch is for use with a running-config on it and because of migration the customer asks me to add the new switch to the existing switch to make a single stack (CoXYZStack).

  I dug around on Cisco's Web site and am not able to find the following Guide Flexstack;

  http://www.Cisco.com/en/us/prod/collateral/switches/ps5718/ps6406/white_paper_c11-578928.html

  Unfortunately, this document is not really detail the configuration that I need a switch? Someone got the configuration Cisco Flexstack experience, if so can you give me some advice on the system requirements on the two switches.

  Basically what is happening, is that both switches act as independent 'stacks' in their own name and I am unable to get them to recognize each other or operate together in one set.

  1 supply ws-c2960s-24pd-l switch
  switch 2 supply ws-c2960s-24pd-l

  I tried the 'x' provision "xyz" switch line configuration on CoXYZSw1, and as you can see when you do a 'detail of switch sho' it shows as provisioned but on the CoXYZSw2 nothing ports battery or battery come off the power ring?

  CoXYZSw1 #sho switch retail

  Switch # Mac address priority Version State role
  ----------------------------------------------------------
  * 1 master c8ba.bf77.1234 14 1 Ready< you="" will="" see="" i="" also="" tried="" altering="" coxyzsw1="" priority="" to="" 14="" to="" ensure="" it="" came="" up="" as="">
  2 Member 0000.0000.0000 0 1 put into service

  CoXYZSw1 #sho switch stack-ring speed

  Speed ring battery: 10G
  Configuration of the stack ring: down
  The ring protocol stack: FlexStack

  CoXYZSw1 battery-ports of the switch #sho
  # Port 1 Port 2 Switch
  --------    ------       ------
  1 down Down

  And as you know the switch does not see or recognize his neighbor? I tried the two possible Flexstack wiring configuratione i.e. battery 1 battery 1 / Stack 2 to 2 and 1 battery battery battery 2 / 1 battery battery 2

  CoXYZSw1 #sho neighboring switch
  # Port 1 Port 2 Switch
  --------    ------       ------
  1 none none

  Anyone has any ideas or a configuration example would be greatly appreciated.

  PS: Also had a trial with this config "stackmaker", but that doesn't seem to help much either? "stackmaker name CoXYZStack.

  You need a minimum of a battery cable is connected.

  Make sure that the 2nd switch DO NOT HAVE any configuration in there.

  And Yes, turn off the switch member of battery 2, connect a cable from the console and it lights up.  After the generated output.

• 2960 x reload command problem

  Hey Cisco,

  I think that I'm not the only one facing this issue when run command reload

  I tested x 2960 as version below

  2015-12 - 18_171716.jpg

  

  normal run charging for Member or another switch of type charging slot 2, it works very well by charging slo type 2

  2015-12 - 18_174901.jpg

  

  When I switch to reload CSL 2, typo invites me error, but seeking to confirm it; In this kind of situation, I just press on enter because I guess I type correctly

  2015-12 - 18_174616.jpg

  

  Surprise, it reload the entire stack switch

  so I test it with the version recommend

  2015-12 - 18_175154.jpg

  

  same question comes, it recharges battery set switch

  2015-12 - 18_175255.jpg

  

  If typo recharge slotx 2, it always reload the entire stack

  2015-12 - 18_184246.jpg

  

  Please consider this question

  Hi Vui,

  The behavior you are observing should because you do not use the correct syntax in order to recharge the required slot.

  The correct command is as follows, please note the keyword exact "slot:

  SWA#reload slot 2

  By typing "charge CSL 2", you say the battery to recharge all members for the reason "CSL 2" which is used management and logging. Please see the following link for more details about this command: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960x/software/15-0_2_EX/stack_manager/command_reference/b_stck_152ex_2960-x_cr/b_stck_152ex_2960-x_cr_chapter_01.html#wp3486313748

• Port Mirroring a LAG on stacked Dell PowerConnect 6248 s

  Hello

  It is possible to port mirror use as a source, a SHIFT, consisting of 4 ports (2 in each Member of a set of 6248 s PowerConnect stacked). Whenever I'm trying to add the source, using GUI, I get an error:

  Error! There not together "Type" with "Tx and Rx" error occurred in FILTER_MISSING

  This allusion is what filter?

  I can't select a spring, unit 1 or unit 2, members of the LAG, like the gui only shows them not from the ports drop.

  Thank you.

  Unfortunately, the switch is able to mirror individual ports as source ports. You can check this by trials of establishing a mirror session where the source port is not part of a LAG.

• Adding to connect 6224 replacement for stacking

  Hello

  We just had a power connect 6224 replaced under warranty.

  -J' removed the stacking of the faulty switch module and installed in the new switch.

  -Power switch replacement and active stacking ports

  -Saved config, power off

  -Attached to the other switch in the stack with stacking cables

  -Powering new switch

  -Master restarted

  -Circuit breaker is backup and running normally, however the Member switch shows "code incompatibility?

  I tried to turn off the Member, remove the Member from the stack, and then restore power (I can not reset the master only outside the hours). But I still get the same code shift.

  Any suggestions?

  Looks like the firmware is not the same. Use the command > view version, to see what firmware the switches are on. The replacement switch must be on the same firmware as the pile. If they do not match, now may be a good time to get them all to date.

• 3424 stack and LAG

  Im doing sort of a proof of concept, and I just want to make sure that this will even work on these switches, because I'm not finding a path in the web interface that makes it look as if it was possible...

  I would like 2 switches on both ends of a connection of the battery and then use a copper and fiber run to a SHIFT to battery. Ideally, I'd put fiber as part of a battery and the copper in the other Member of the stack. This way if I lose a member, I always one connection through the other.

  Best as I can tell, the ports of battery works very well in that I can get a master light on one and one ID on the other. But I'm not sure I see how to specify in the stack, the LAG exists in a way such that it is on each of the switches.

  But with the LAGGY menus, it looks like im only able to specify the ports 1-8 and no ports G.

  I'm too complicate this and missed something simple or and I just totally out of the way?

  Well apparently my just stacking was not not display correctly... I made a start of led and was able to successfully achieve my pile of numbering.

  After that, the interface switch stacked came on menus LAG and I was able to set the time to wait/priority/etc very well.

• Error stack N2048P

  I have 2 stacked N2048P switches. Shortly after the deployment, I started to have constantly the errors below:

  DRIVER 172.x.1.x - 2 [108576100]: broad_hpc_drv.c (4362) 8073 %% unit: 0

  CDC RX FIFO entry error 37 double-bit ECC

  Here are the nine switches configured by Dell. I'm not familiar enough with the operating system to solve problems. Everyone knows this? If so, how to solve it?

  Hi chanjohn01,

  The error is a memory error. You can try to update or Flash the image and see if that helps. http://www.Dell.com/support/home/us/en/19/drivers/DriversDetails?driverId=Y7V3N&FILEID=3376784553&osCode=NAA&ProductCode=networking-N2000-Series&LanguageCode=en&CategoryID=NI

  If this does not resolve the problem, try unstacking and ensuring that it is just the first member of battery that is giving the issue, the error refers to unit 0.

• Dell PowerConnect 7048 P reference stack Questions

  Hello

  I have two switches in L3 7048P I want the battery but I'm not sure how it works. The two switches have the same firmware.

  1 must. the two have the same configuration running on both to make it work?

  2. in addition, I created a VLAN (3) voice on the first switch with an IP address of 10.0.3.254. I use the same IP address on the second switch in the VLAN 3 addresses or assign another?

  Thank you!

  There is a guide especially for stacking switch 7048 on the Dell page networking white papers:

  en.Community.Dell.com/.../2580.Networking-guides.aspx

  Just search "Dell PowerConnect 7000 Series Switches stacking".  Page 16 will tell you how to add a new Member to the battery with minimum interruptions. Both can present the same firmware in order to stack.  So the answer to question 1 is no, the configurations do not need correspond to stack them.  Once stacked, both will look like a single switch, and you use only the IP address of the master swtich to the whole stack.  Therefore, treat the two switches as a single switch during Setup.  The guide provides more information on how it works.

  Hope this has been helpful.

• Member of the main force in a pile of N2000

  Hello

  I have a stack of switches N2000. For fair and easy management I want to force the master to a particular switch do not rely on higher MAC or other options in the manual.

  Is my question, possible to force a master member into a pile of N2000/N4000?  (I read on the failover standby and initiate force, but it is not a good enough solution for me).

  Kind regards

  Hello

  I confirm, renumber ID does not affect the election of master. There is no way to force the election of master.

  In any case, becomes the ID is just enough to switch identification which was my goal prymary.

  Kind regards

• What are the bare minimum commands to get a stack of PC6825 3 - switch with inter switch Link Aggregation?

  I am brand new to PowerConnect switches, even though I am familiar with the concepts of VLANS, aggregation of links and spanning tree.

  I am on a deadline to get some new ones installed 6248 in our baskets and get them functioning as a stack. What are the bare minimum commands for:

  • Three switches in a stack (master/Eve/member)
  • 2 ports grouped between each (total redundancy) switch with loops WITHOUT switching

  All the switches are running firmware v3.3.9.1 (January 2014).
