Access Line Port ASE Circuits
PVC IP HDLC ATM
Application Alarms are generated nightly during
the Daily Database Maintenance.
14
Service Summary Polling
On the Visual UpTime Select server, the Service
Summary process polls ASEs for status data every
15 minutes (this setting can be changed in Server
Administration on the server). A Service Summary
middleware component in the server requests
updates from the poller every 15 minutes and
interfaces with the Web Server to make detected
ASE status changes available to Web Clients.
Server polls ASE every 15 minutes (default) for
up/down status. Useful for HARD OUTAGES or cuts
on the circuit. Web Client automatically
refreshes, globally, every 300 seconds (default),
or a manually with the REFRESH button.
Select Server

• Service Summary data includes
• Updates of layer 2 up/down status on
  ASE-monitored ports polled from ASEs every 15
  minutes and circuit up/down status polled every
  hour.
• Port history (link up/down status) stored in
  1-hour intervals for the most recent three days.
• The five most recent port and circuit events
  uploaded by ASEs, updated every 15 minutes or
  when you refresh the Port and Circuit Details
  page in Service Summary. An ASE uploads recorded
  events as they occur to the Service Summary
  process in the Visual UpTime Select server and to
  the network performance database. To view all
  events for the previous two weeks, use the PAC
  Event Processor.

15
Network Configuration Requirements

• User must have the Platform Applicable Client
  (PAC) loaded on their PC or access via Remote
  Terminal Services.
• User must have connectivity from the PAC to the
  Select Server.
• Note Firewall configuration for PAC lt-gt Server
  communication necessary.
• User must have Network Configuration user access
  on the Domain, i.e. Customer.
• The ASE probe must be installed at the customers
  premise.
• The Select Server must have connectivity to the
  ASE probe.
• Note Firewall configuration for ASE lt-gt Server
  communication necessary.
• Proper licensing must be deployed on the Server
  (or the Domain) in order for the ASE probe to be
  added for monitoring.
• DOMAIN
• A logical partitioning of all networks
  configured on a Visual UpTime Select server. A
  user can have access to more than one domain,
  and a domain can be accessed by multiple users.
  The Visual UpTime Select administrator configures
  which toolsets and functions a given user can
  access by domain.

16
Decisions to be made The only fun part

• The Customer Data is segmented by the following
• SERVER (the highest level, encompasses the
  server and all the Domains/Customers within the
  Server)
• DOMAIN This is typically the Customers Name.
• example GlobalFinacials
• NETWORK This can be a single Network or multiple
  Networks
• example GlobalFinacials
• Or
• example Asia Network, US Network, South America
  Network, Europe Network
• SITES This can be the Physical Location of the
  ASE, or LEC Circuit ID.
• example Rockville MD
• ACCESS LINES This is also equal to PORT. The
  actual IP Address of the ASE is provisioned here.
• CIRCUITS Mapping of two ASEs to each other to
  create an IP Circuit, PVC, HDLC, or ATM circuit.

17
Example and Notes

• Server 192.168.236.46
• Domain
• GlobalFinancials
• Network
• Global Financials
• Site
• Rockville MD
• Access Line
• RTR123CKTid
• Circuit
• RockvilleMDlt-gtEverettWA

• NOTES
• User Access is controlled at the Domain Level,
  not the Network.
• WAN Planning and Reporting has the option to
  generate Reports on All Networks, or specific
  Networks like ASIA Network or US Network.
• Sites can have more than one ASE, in the case of
  multiple Access Lines.
• Access Lines is where the ASE IP address lives.
• Circuits must be mapped correctly and MACDed if
  changed in reality on the network.

18
PAC Log in

• 1. Navigate to START? Program? Visual Networks
  ?Visual UpTime Select Client ?PAC

2. Click ADD
3. Name Server and input IP address
Any name will work. It is local to the Client.
Successful ?PAC attempts to contact server.
4. Highlight Server and click CLOSE
5. Login with provided User name and Password
Steps 1-4 will be skipped next time you log in.
19
To switch customers 4 clicks

• Once log ined it is very easy to change
  customers for a MACD within the Network
  Configuration toolset.

A. Login? Setup? Domain Selection

B. All Servers and Domains that the USER has
access to is populated in the Domain Selection
screen.

Network Configuration
1.

• Click Network Configuration
• Click Add Networks
• Click Add Sites
• Click Access Lines Port ASE more work needed
• Click Auto Add must be correct
• Click Close

Best Practice Print...to file and save the
Domain Configuration for backup.
21
Add Access Line Port ASE

• Add the Access Line Name
• Decide on Data Collection
• Add the LAN IP or INBAND IP address of the ASE.
• Click ASE Setup
• This will cause the Select Server to contact
  the ASE to confirm communication and license for
  monitoring.
• Best Practice Fat fingering the IP address of
  the ASE will cause failure, as will, no IP route
  between ASE and Select Server, as will, the wrong
  SNMP Community string in the CLI of the ASE.
• Best Practice Collect Data more often than
  once a day for locations with known power
  outages or generators.

1.
4.
2.
Always, Always do a Data Collection prior to
rebooting or updating an ASE.
3.
Best Practice1 Set the Data Collection to the
ASE Local Time based upon the Server Time. Best
Practice2 If ASE is not installed or down, make
the ASE Active checkbox inactive (grey).
22
ASE Configuration

• IP... Lots of Action Here
• Frame Relay... hmm, interesting
• T1 Interface... DO NOT MESS WITH. This is the
  T1 command on the ASE. Not applicable on probes.
• ________________________________________________
• Software Version
• IP Transport ASE MPLS IP VPN Networks
• Multi-Protocol ASE Traditional Frame, ATM, HDLC
  Networks
• Same Hardware, different Firmware

Buttons depends on the type of ASE
T1 Interface The most dangerous button
The ID command on the ASE
Good info
Same as Serial
or Multi-Protocol
or Multi-Protocol
Do Data Collection first, requires a reboot.
Best Practice Always confirm the latest Software
Version during installation by checking Visual
Customer Care (VTAC).
23
T1 Interface
The T1 Command on the ASE is used to configure
the CSU/DSU.

The PAC ASE Setup T1 button allows for editing
the CSU/DSU configurations. Best Practice On
circuit upgrades, change the CSU/DSU via command
or PAC prior to upgrading the circuit.
Communication will be lost with the ASE until the
circuit is upgraded and the CSU/DSU becomes
synchronized.
This information is provided by the local Telco
and must match in order to work, otherwise truck
roll.
NOTE Any T1 Command Line or PAC changes are
instantaneous. Double check.
24
Frame Relay

• Frame length gt than 4096 can be viewed under
  PORT? STATISTICS
• Enscapulation Protocols are for those tricky
  moments
• Link Management is standard LMI between the CER
  and the PER.

25
IP...Applications

• Top 10 Applications will be rotated every 7 days
  unless LOCKED.
• Use LOCK for your favorite protocols.
• Auto Select should be used initially for every
  install.

Very cool feature Auto discovery and monitoring
of the top 10 Protocols for the week.
26
IP...Subnets

• Subnet Guidance List is a suggested discovered
  subnets that the ASE automatically discovers.
• If BGP is being used, the Local Subnet List will
  be automatically populated.
• The subnets related to the Customers Routers
  Serial interface should be used.

These Local Subnets will be mapped to another
Remote Local Subnet to create an IP CIRCUIT.
Customize your local subnets
THE LOCAL SUBNET LIST MUST BE CORRECT IN ORDER TO
MAP AN IP CIRCUIT AND GAIN PROPER COS SLA METRICS.
27
IP...Class of Service

• The CoS Configurations default configuration is
  set on the Select Server for each Domain.
• Getting it right in the Select Server will get it
  right on every ASE.
• Each field is configurable on the server.
• Only Policing Threshold settings for each CoS is
  configurable here.

Reminder All traffic is tagged in the ToS on
the Customer Edge Router, the ASE is only
monitoring the ToS field. If the Web Client
shows Unknown then the CER is typically
mis-configured because all traffic is tagged as
best effort.
Up to 8 CoS settings can be configured. Jitter on
CoS only available once.
28
IP...Committed Access Rate (CAR)

• CAR values are represented at the PORT? BURST
  tab.
• In some ASEs, like the Ethernet ASE, the CAR
  value is also used in the PORT? Summary tab for
  PORT Utilization graphing and reporting.
• This value is only used for calculations and
  reporting.
• This values does NOT affect traffic.
• Setting to zero will default to ASE Port Speed.
  

The GREAT DEBATE In some cases, CAR PORT
speed, in other cases CAR the value
guaranteed by the Service Provider on the Local
Loop. Also known as the policed value as
related to the Port NOT CoS.
29
IP...IP Circuit Clean Up

• IP Circuit Clean Up an easy way to delete
  non-functional, or mis-configured IP Subnet to IP
  Subnet mapping.

30
Creating IP Circuits

• AUTO ADD SHOULD NOT BE USED ON REMOTE SITES and
  only on LIMITED HUB SITES
• This creates a fully meshed environment that may
  not be accurate with the routing statements.
• BE VERY CAUTIOUS HERE.

31
IP Circuit Properties

• This screen is useful when BGP is running on the
  network. If you see red, check the square and
  close. Click OK, close, and re-open.
• IF BGP is not running, much more consideration
  needs to takes place in creating an IP Circuit.

Best Practice Use the ADD button in the Circuit
Network Configuration to make an educated IP
Circuit mapping proper subnet to subnets
32
PAC Identify ASE
1. Log into PAC and go to File gt Identify ASE
Identify ASE only available on the PAC.
IP Class of Service settings are configured on
the Customer Domain by the Server Administrator.
4.
2.
3.
By getting it right in one place, the ASEs
will track COS and thresholds for all Sites.
33
PAC System Management
Best Practice

• Run Identify ASE often, especially after
  upgrading an ASE, or the Select Server.
• Run ASE Inventory to better understand your
  connection status.
• Run Collect Data Nowon individual sites,
  especially if Data Collection Poll Failure Event.
  
• Search for DATA COLLECTION POLL FAILURES Partial
  Data Collection in the Event Processor means
  mis-mapped circuits and are not good. Fix these
  ASAP in Network Configuration, or open a ticket.
  This effects SLA metrics.

Log into PAC and go to File
34
Review

• Use the PAC to run Identify ASE and Data
  Collection to quickly assess the monitoring of
  your Visual Select system.
• Search for Data Collection Poll Failures and fix
  these immediately on the Circuit in Network
  Configuration or by opening a ticket.
• Sort the Events by Site or Priority for quick
  site analysis.
• Use the Acknowledge Displayed to remove Events
  from the Event Processor and keep the Events
  manageable.
• Use the context sensitive HELP system.
