Advantages of 10/100 Management port on 6500/4500 series

Hi mates,
There is a common port called "10/100 MGT" (next to console port) on the supervisor engines of 6500 and 4500 series switch.
Why would I need that port since I can telnet through Layer2 10/100 ports??
Is that port doing the same job as console port? in addition allows longer distances over cat 5 cables??
Do we need to assign IP address on that mangement port?
Thanks for helping :)

Hi,
The 6500 supervisors do not have a 10/100 MGT port. The cat4000 supervisors do, however.
On the supI and supII, the Ethernet management ports are for network management only. These ports do not support network switching. See:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat4000/inst_gd/05modins.htm#xtocid184774
On the SupII+, SupIII, and higher, the Ethernet management port is used (in ROMMON mode only) to recover a switch software image that has been corrupted or destroyed due to a network catastrophe. This port is not active while the switch is operating normally.

Need SNMP MIB files For Cisco SF 300-48 48-Port 10/100 Managed Switch

Hi All,
I need SNMP MIB files for Cisco SF 300-48 48-Port 10/100 Managed Switch.
I have gone through cisco site but not able to get it.
Can anyone please provide me.I have stuck with this.
Thanks
Ram

Hi Ram, yes the MIB can be used. The switches are essentially the same in many regards (especially on a software level).
I do not know the OID for bandwidth. If you're looking for a particular OID may be this tool helps you

Cisco 3850 Switch Management Port - ACL on VTY

Hi,
I got these switches.

If I remove the ACL under VTY "no access-class ACLVTY in", then SSH to the management port works. If I don't use the management port and use a normal port say G1/0/1 configured on management VLAN and assigned the same IP address, then SSH works with the VTY ACL still existing.
Any ideas ?
Thanks,
Rick.

Hi,
IOS will accept all VTY connections by default. However, if an access-class is used, the assumption is that connections should only arrive from the global VRF. If you need control the IP source while allowing VTY connections from VRF instances, you have a try configuration option "vrf-also"
So, you should get something like this:
line vty 0 4
access-class ACLVTY in vrf-also

Re-addressing of WAE's management port

Hi,
I would like to re-address management port of WAE. What is the correct method for doing it? Because the WAE is registered in the central manager WAE. When I re-address management port of WAE, the central manager has problem with the new address. Thank you.

I would probably restore it to factory defaults and then go through the normal configuration process:
# restore factory-default
This clears the unit and then it will reboot.
When it comes back up, you configure the interfaces:
(config)# interface GigabitEthernet 1/0
(config-if)# ip address X.X.X.X X.X.X.X
Duplex is automatically at 1000 full. If something else is required, add the following (as appropriate):
(config-if)# bandwidth 100
(config-if)# full-duplex
(config)# ip default-gateway x.x.x.x
(config)# ip name-server x.x.x.x
(config)# ip domain-name myDomain.com
(config)# host myHost
(config)# clock timezone US/Eastern -5 0
(config)# ntp server x.x.x.x
(config)# show clock (verify Timezone settings)
***You still need this next line even if you are using inline cards
(config)# primary-interface gigabitEthernet 1/0
(config)# central-manager address x.x.x.x
(config)# cms enable
If cms registration isn't successful, try burning the config to flash and doing a reload. Then reattempt and it should work. The WAE must be connected to the network and able to communicate with the Central Manager for the âcmsâ command to work. It fails because it can't generate the certificate. Timeout is 15 seconds and states it was âunable to register.â
Once the cms enable is successfully completed, a reload is a good idea.
Hope this helps.

3560 and 3750 - Question about 10/100/1000 ports

I am researching several Cisco products to recommend to a customer. I was wondering if the 10/100/1000 ports at a 3560 switch, will provide gigabit bandwith on each port or if the bandwidth is shared among several ports. The latter is how a 48 port 10/100/1000 line card would behave on a Cisco 4500 when, depending on the card, the gigabit bandwidth will be shared among 4 or 6 ports at a time.
What about 10/100/1000 ports on a 3750?
Thanks

The new Catalyst switches/modules such as the Catalyst 6500/6000, 4500/4000, 3550, and 2950 support 10/100/1000 Mbps negotiated Ethernet interfaces or ports. These ports work on 10Mbps, 100Mbps, or 1000 Mbps speed based on their connection to the other end. These 10/100/1000Mbps ports can be configured for speed and duplex negotiation in the same way as 10/100 Mbps ports on CatOS or Cisco IOS Software-based switches. Therefore, the configurations given in this document for 10/100Mbps port negotiation applies to 10/100/1000Mbps ports as well.

Linksys Cisco SRW248G4P 48-port 10/100 + 4-port Gigabit Switch Help

The switch which is a Linksys Cisco SRW248G4P 48-port 10/100 + 4-port Gigabit Switch, was configured by a contractor which was long ago run off, and the documentation left behind to log into the switch is incorrect. How can we reset this switch so we can configure to the new required settings?
I have attempted to go in through the web browser gui, and no luck logging in via factory default creditials, cannot log in using any of the common admin creditials, nor can we get in via the documented admin name and pw the contractor left.
Attempted ot go in through the console, that doesn't work right at all. Takes 15-20 min before I start even seeing user name or password boxes. Cannot type a single thing into those boxes. I have set the hyperterminal to com1, 38400, 8, none, 1, hardware. It kinda lets me see some of the log in screen, but will not let me type into the username whatsoever.
Logging via web browser I see all the login option but not a single username or pw works. Please if anyone can help, this has been an issue which is now critical.

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center.
The settings for connection using Hyperterminal through the Console port should be:
Bits per second: 38400
Databits: 8
Pairity: None
Stop bits: 1
Flow Control: None
When you finish configuring the HyperTerminal, the Login screen appears. The first time you open the Console Interface, use the default username admin and leave the password blank and press the Enter key. You can set a password later from the User and Password Settings screen.The Main Menu screen displays six menu choices: System Configuration Menu, Port Status, Port Configuration, PoE Configuration, Help, and Log Out.
User and Password Settings, IP Configuration, File Management, Restore System Default Settings, Reboot System and Back to Main Menu.
To restore the Switch back to the factory default settings, select Restore System Default Setting and press Enter. A confirmation message appears asking Are you sure? [Y/N]. Press the Y key to continue or the N key to cancel the action.
System Configuration Menu options: (Which is where you will need to go) consist of: System Configuration, Management Settings
After pressing Y, at this point reboot your system and it will be back to Factory Fresh.
If you have any questions or this doesn't work, please let me know. I am attachng the Admin Guide for you as well.

To drive a monitor from a Mini, is there an advantage to using the Thunderbolt port versus the HDMI port?

Is there an advantage to using the Thunderbolt port versus the HDMI port to drive a monitor?
Can i just plug in my 18" LCD TV to the HDMI port and use it as a monitor?
Thanks, friends ~

Thanks, lllaass,
I have a new Mini arriving tomorrow. It will be replacing my 9 year old iMac.
I have at my disposal an older VGA monitor and a regular LCD TV with
an HDMI input. I'm trying to decide which one will work the best for me. If I use the TV, I won't have to buy
a Thunderbolt to VGA adapter.

Half duplex or full duplex configuration for MDS9124 management port?

Hi All,
Is it possible to set the management port of mds 9124 about half or full duplex configuration?
I want to correct following error:
Jun 13 10:27:20.799 GMT: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on GigabitEthernet4/18 (not half duplex), with mtw1pc02bs0(FOX1450G8QG) mgmt0 (half duplex).
it seems mds 9124 set his port to half duplex.
Dennis

You may want to check this thread :
https://supportforums.cisco.com/thread/2059109
Else try the following :
switch# config terminal
switch(config)#
switch(config)# interface mgmt0
switch(config-if)# switchport duplex full
switch(config)# exit
switch#
switch# copy running-config startup-config
Also, I would suggest you check what the counterpart of your MDS switch mgmt interface is set to (i.e. is it set to autoneg, then try setting it to fix speed/duplex or the other way around).

Question about 4500X VSS management port

I have two standalone 4500X switches that I'm planning to convert to VSS. If I cable the management port on both switches to a management cloud, which management port should I put the management IP address? Is it the port on the active switch? if the active switch failed, would the management port on the standby switch take over the management IP?
The management port is in VRF mgmtVrf. Should I create a default route for the VRF such as "ip route vrf mgmtvrf 0.0.0.0 0.0.0.0 ....." to point to its default gateway IP?
Thanks

When you convert the chassis to VSS, only the management interfaces (FastEthernet1) for switch-1 (active) will be visible in the config. So you want to cable both management interfaces to your management cloud, but you only apply the IP to the active switch.
The management port is in VRF mgmtVrf. Should I create a default route for the VRF such as "ip route vrf mgmtvrf 0.0.0.0 0.0.0.0 ....." to point to its default gateway IP?
Correct, you need a default route in that mgmt vrf pointing to the gateway.

Management port on CSS 11150

I have a simple question. Can someone tell me how to access the management port on the css 11150?
I configured the ip and mask on the management port and condigured my laptop for a ip on the same network. But i am unable to connect.

what do you mean by connect ?
Are you trying telnet or HTTP ?
Are you able to ping ?
Is the interface showing up ?
Try 10Mb Half duplex set manually and see if it works.
Also, did you reboot the CSS after configuring the ip address/mask for the management interface ?

How to manage port open/close on MacMini server

Dear all,
In order to secure my server, I discover than some port are open.
Is there a way to close all port and open only 445 and 548.
I would like to make sure that no body can access the server from outside of the society ecepted if the have VPN client configured.
The collaborator should be able to connect the server via afp, but form out side they need to use VPN.
Then I am looking for a way to manage port on macmini server
Many thank for your help
Cheers

Hi,
I finally heart that port can not be closed on the router because I am usinf 1:1NAT.
How can close all port on my Macmini and open only the port ssh. I will not use VPN.?
If I turn on the firewall with the option to close all protocole. Is there a command to open a selected port?
If there is only the port 22 (SSH) how can I mount a remote folder with afp or with somethin else? I also have on PC over the 7 iMac.
Many thank for your help
Cheers

Output drops on cisco link connecting to F5 Loadbalancer's management port

On a connection like below:
Cisco 6509: gi x/y <<-->> F5 BIGIP LTM: mgmt (Management Port)
We observed incrementing packet drops on the F5 BIGIP mgmt interface.
Also, at the cisco end, incrementing output drops were observed.
tcpdump (packet capture) on the F5 BIGIP's mgmt port show brodcast packets/ multicast including the HSRP hellos being received from the cisco device. It is an expected behaviour that, F5 will reject any packets it cant understand (including the cdp, hsrp and other broadcast), and this will cause the packet drop counter of F5 BIGIP's mgmt port to increase. (F5 TAC acknowledged this behaviour)
Will this cause the output drop counter at the cisco interface to roll up?
Note: On the cisco interface, i do not see any other errors, also utilisation on the link is very minimal.
Thanks
Sudheer Nair

Hi, this is probably late, but the software counters for output drops on these types of switches (3750's, blade switches) are not reliable.
What you need to check is "show platform port-asic statistics drop" for a reliable drop counter on an interface. This will give you the hardware counters
https://tools.cisco.com/bugsearch/bug/CSCtq86186/?reffering_site=dumpcr
Switch stack shows incorrect values for output drops/discards
on show interfaces. For e.g.,
--- show interfaces ---
GigabitEthernet2/0/5 is up, line protocol is up (connected)
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 4294967163
Conditions:
This is seen on Stackable switches running 12.2(58)SE or later.
Workaround:
None.
