It's Monday, you've not yet had coffee and the week ahead is gonna suck. Lets open the floor for a weekly Stupid Questions Thread, so we can all ask those questions we're too embarassed to ask!
Post your question - stupid or otherwise - here to get an answer. Anyone can post a question and the community as a whole is invited and encouraged to provide an answer. Serious answers are not expected.
I have a test DMP 4310G that I’ve got my hands on for a while to see functionality, but I’ve learnt that I need the software (DMPDM) firmware release 5.2.2 to set it up to use etc, but I didn’t realise I need a Cisco valid service contact to make it all work. Could someone please gratefully share the software for this device. (bit.ly/2HSEX14)
I have a OSN 1500B configured two Q5CXLL16(L-16.1,LC), does this mean that the OSN can support a total of 32 STM-1/8xSTM-4? This is assuming that the box has the ability to support 8 STM-4 interfaces.
I have several customer that need secure guest networks - I am looking for a simple device that I can pre-configure and connect to the network to provide this, but I've been unable to find a fully secure solution.
I've tried several different routers, different firmwares including custom open-source, and I cannot get the wired devices fully isolated from the wireless connection. I have tried configuring with VLANs, and guest/hotspot options, but none of them stop me being able to ping the local wired devices.
I've spent a lot of time on this and can't seem to find any solution that is 100% isolated - can anyone provide any insight for me? I'm no engineer/expert...
Hey all,
I'm in the process of working out which switches will fit our requirements, and seem to be having a derp moment.
I want to confirm that all 48 1Gbps ports on a 2960-X (Lan-Base) + 2 10Gbps uplinks can operate at line rate.
I believe I've confirmed this by confirming the switching bandwidth of 216Gbps.
(Data sheet: https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-x-series-switches/data_sheet_c78-728232.html)
I've confirmed that 2Gbps (full duplex 1Gbps) * 48 (Ports) = 96Gbps, and with the two 10Gbps uplinks = 136Gbps, plus stack of 80Gbps full duplex = 216Gbps which matches the switching bandwidth. That makes sense.
Where I'm having issues is when looking at the Mpps table.
It says 130.9Mpps is possible on the Cisco Catalyst 2960X-48FPD-L model with 64 byte packets.
I'm getting confused relating the Mpps to the switching bandwidth. How can I calculate how many Mpps at various packets sizes? How can I find the maximum Mpps for the switch? Does this relate to the Switching Bandwidth at all?
G'day guys, apologies if this is already in here I've gone through the search and haven't been able to find what I'm after (I'm sure it is just my wording).
I'm trying to come up with a solution to keep track of when my multicast traffic is coming in or not. I don't care about the data itself, I just need to be able to pinpoint if and when I am receiving the traffic. Are you guys doing anything similar? If so what do/would you use?
Thanks
I've seen fiber cuts due to back hoes, drivers hitting telephone poles, data closets getting flooded, rodents chewing through wires, etc...
I just saw this image on the front page: http://i.dailymail.co.uk/i/newpix/2018/05/06/03/4BE7272900000578-5695425-image-a-37_1525574205390.jpg
What's your "best" root cause item for an outage?
A couple years ago I released a tool on github and Reddit (thread) to automatically discover and diagram your network. Give this python script an IP address of a root node and SNMP read-only credentials, and it will do the rest.
Version v0.10 is now on github.
Change Log
v0.10 - 5/5/2018 - Ported to Python 3 - Cleaned up and refactored code - Improved discovery - Improved discovery console output - Fixed VSS chassis detection; now finds correct serial# and platform - All output referencing node IP now uses best IP instead of first found - Try all known IPs for a node until one works; no longer fails on unreacable IPs (eg, VRFs/ACL blocks/etc) - Default depth is now 100 - Added runtime to stdout - Renamed 'graph' to 'diagram' - Cisco ACL-style node matching (replaced config subnets/exclude with discover) - Added 'leaf' option to stop discovery beyond a matching node - Added 'include' option to stop discovery at a matching node - Config option diagram/node_text replaces the below: - include_svi - include_lo - include_serials diagram - Changed -f option to -o - If a LAG spans multiple devices (eg, Nexus) override expand_lag for that device - Output can create multiple files. Ex: -o "file.{svg|png}" will create file.svg and file.png
Example
# ./mnet.py diagram -r 10.75.0.1 -o .\network.svg
Will generate this diagram.
So I'm upgrading my home network and I need some advice on a router, I've had a look at tp link and netgear but can't find anything specific.
So I turn to you, the Internet for advice.
I mainly use it for streaming HD films from my pc to my 2 raspberry pi's but I don't mind doing this wired if needed. I play ps4 online and just general day to day stuff on my phones/tablet and laptop, stuff like youtube and general Web browsing.
Can anyone help me with options to achieve this.
